			<description><![CDATA[In a previous editorial, I had promised to explain the new open call process for Associate Technical Editors (ATEs). This open call process was initiated by our Com- Soc past president Byeong Gi Lee with the goal of making a fair and straightforward mechanism to bring new editors into all the various ComSoc journals and magazines. It took some time to create a common web site that can be used for all the publications, and to work through the specific implementation for Communications Magazine. The process is now fully in place for Communications Magazine and will be described here.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6146464&arnumber=6146481]]></link>
			<description><![CDATA[Optical networks are undergoing significant changes, fueled by the exponential growth of traffic due to multimedia services and by the increased uncertainty in predicting the sources of this traffic due to the ever changing models of content providers over the Internet. The change has already begun: simple on-off modulation of signals, which was adequate for bit rates up to 10 Gb/s, has given way to much more sophisticated modulation schemes for 100 Gb/s and beyond. The next bottleneck is the 10-year-old division of the optical spectrum into a fixed ??wavelength grid,?? which will no longer work for 400 Gb/s and above, heralding the need for a more flexible grid. Once both transceivers and switches become flexible, a whole new elastic optical networking paradigm is born. In this article we describe the drivers, building blocks, architecture, and enabling technologies for this new paradigm, as well as early standardization efforts.]]></description>

			<description><![CDATA[As traffic demands continue to grow, supporting data rates beyond 100 Gb/s will be required to increase optical channel capacity and support higher-rate client interfaces. Advanced modulation formats that adapt to optimize spectral efficiency over a range of channel signal-tonoise ratio conditions are required. Channels can be constructed by varying parameters such as symbol rate, bits per symbol, number of polarizations, and number of optical and electrical subcarriers. Channel capacity can also be increased using advanced techniques such as optical time-division multiplexing, and fibers that support multiple cores and modes. Many channel designs can support higher data rates, but there are trade-offs between complexity, spectral efficiency, and optical reach.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6146464&arnumber=6146483]]></link>
			<description><![CDATA[Optical fibers have often been considered to offer effectively infinite capacity to support the rapid traffic growth essential to our information society. However, as demand has grown and technology has developed, we have begun to realize that there is a fundamental limit to fiber capacity of ~ 100 Tb/s per fiber for systems based on conventional single-core single-mode optical fiber as the transmission medium. This limit arises from the interplay of a number of factors including the Shannon limit, optical fiber nonlinearities, the fiber fuse effect, as well as optical amplifier bandwidth. This article reviews the most recent research efforts around the globe launched over the past few years with a view to overcome these limitations and substantially increase capacity by exploring the last degree of freedom available: the spatial domain. Central to this effort has been the development of brand new fibers for space-division multiplexing and mode-division multiplexing.]]></description>

Polarization- division multiplexed quadrature phase shift keying with digital coherent detection, and fast recovery in optical channel rerouting are key technologies for 100-Gb/s long-haul systems and beyond. We review test results of a realtime 80-channel wavelength-division multiplexing transmission over 420 km of field-installed fiber. Finally, we focus on digital nonlinear compensation and pilot tone phase noise compensation as technologies for systems beyond 100 Gb/s.]]></description>

			<description><![CDATA[Major client optics applications are the highdensity data center, structured data center, carrier central office, general data center, and metro inter data center, corresponding to link reaches from 100 m to 40 km. First-generation 100G multimode fiber and single-mode fiber client optics are based on 10 ?? 10G electrical lane and 10 ?? 10G or 4 ?? 25G optical lane architectures. Next-generation 100G MMF and SMF client optics will be based on 4 ?? 25G electrical lane and 4 ?? 25G optical lane architecture. Beyond 100G, it is likely the next standard will be 400G based on extensions of 100G technologies. Beyond 400G, 1.6T is a possible standard, requiring highly novel technologies.]]></description>

			<description><![CDATA[Five criteria that are usually considered by IEEE standards committees for development of next generation standards are broad market potential, distinct identity, and compatibility, as well as technical and economic feasibility. We consider these criteria separately and show that the new emerging large-volume markets loosely defined as Computercom will demand new standards and new technologies. We discuss how the balance between single-channel bit rate, and number of wavelength multiplexed and spatially multiplexed optical channels can help to satisfy the need for huge total bandwidth, while keeping cost low and power efficiency high. Silicon CMOS-integrated photonics holds promise to become a technology of choice for wide deployment of low-power and cost-effective optical interconnects for these new markets, and to become a single solution addressing distances spanning from just a meter to 10km.]]></description>

			<description><![CDATA[The Release-10 LTE-Advanced (LTE-A) is a major enhancement of the Long Term Evolution (LTE) standard developed by the 3rd Generation Partnership Project (3GPP). LTE-A was ratified by the International Telecommunication Union (ITU) as an IMT-Advanced (fourth generation, 4G) technology in November 2010. The 4G objective is to meet challenges presented by the ever increasing use of ??smart?? wireless devices that require significantly higher spectral resources than conventional cell phones. LTE-A addresses those challenges by targeting peak data rates up to 1 Gb/s with up to 100 MHz supported spectrum bandwidth and by making use of high-order multiple-input multiple-output (MIMO) transmission with up to eight spatial layers on the downlink and four spatial layers on the uplink.]]></description>

			<description><![CDATA[LTE-Advanced extends the capabilities originally developed in LTE within the 3GPP. Carrier aggregationis the most significant, albeit complex, improvement provided by LTE-Advanced. Bandwidths from various portions of the spectrum are logically concatenated resulting in a virtual block of a much larger band, enabling increased data throughput. Additionally, enhancements to MIMO antenna techniques in the uplink and downlink further increase the data throughput. Cell coverage is improved by means of relay nodes, which connect to donor eNode-Bs. To cope with the many varieties of cell types and sizes (macro, pico, femto), intercell interference control is enhanced to handle these heterogeneous networks. Operators hope to leverage LTE-Advanced to offer their mobile wireless customers a vastly superior user experience.]]></description>

			<description><![CDATA[LTE and LTE-Advanced have undeniably provided a major step forward in mobile communication capability, enabling mobile service provisioning to approach for the first time that available from fixed-line connections. However, market demands typically do not evolve simply in discrete steps; therefore, the future evolution of LTE-Advanced will be a story of continuous enhancement, on one hand taking advantage of the advancing capabilities of technology, while on the other aiming to keep pace with the expectations and needs of the end users. In this article, the likely directions of this continuing enhancement are discussed, and some areas where further technical advancement will be required are identified. In particular, potential measures to enhance the efficiency of spectrum utilization by joint multicell optimization, dynamic adaptation of the network to traffic characteristics and load levels, and support for new applications are highlighted.]]></description>

			<description><![CDATA[3GPP LTE Release 10 standards (also known as LTE-Advanced) adopted some of the state-ofthe- art radio access technologies that include carrier aggregation, eight-layer downlink spatial multiplexing, and four-layer uplink spatial multiplexing. For facilitating these enhancements, reference signals have significantly evolved in LTE-Advanced. This article examines underlying design principles of the LTE-Advanced reference signals. Specifically, newly introduced dedicated demodulation reference signals and channel state information reference signals for downlink and improvements of demodulation reference signals and sounding reference signals in uplink are discussed.]]></description>

			<description><![CDATA[Single-user multi-antenna technologies are well upported in current standard specifications like LTE Release 8/9. Further development of the specification (LTE-Advanced) is expected to conform to the requirements for IMT-Advanced systems. One of the key enabling features of LTE-Advanced to meet IMT-Advanced downlink performance requirements is multi-user MIMO, where a transmitter serves multiple users simultaneously on the same frequency resource, primarily relying on spatial separation. In general, multi-user MIMO is beneficial for improving average user spectral efficiency. However, cell edge user spectral efficiency may be reduced if multi-user MIMO is used exclusively, due to residual inter-user interference arising from practical multi-user beamforming and reduced transmit power allocated to each user. Therefore, it should be possible to configure the UE-specific transmission mode to support dynamic switching between single-user MIMO and multi-user MIMO to balance the cell edge user spectral efficiency as well as the average cell user spectral efficiency. In this article, we study various aspects of multi-user MIMO including design philosophy, multi-user precoding, and control signaling. The associated feedback schemes, including those that facilitate dynamic switching, are discussed. Performance evaluation is conducted to demonstrate the gain of dynamically switched single-user and multiuser MIMO as opposed to traditional single-user MIMO.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6146464&arnumber=6146494]]></link>
			<description><![CDATA[3GPP has completed a study on coordinated multipoint transmission and reception techniques to facilitate cooperative communications across multiple transmission and reception points (e.g., cells) for the LTE-Advanced system. In CoMP operation, multiple points coordinate with each other in such a way that the transmission signals from/to other points do not incur serious interference or even can be exploited as a meaningful signal. The goal of the study is to evaluate the potential performance benefits of CoMP techniques and the implementation aspects including the complexity of the standards support for CoMP. This article discusses some of the deployment scenarios in which CoMP techniques will likely be most beneficial and provides an overview of CoMP schemes that might be supported in LTE-Advanced given the modern silicon/DSP technologies and backhaul designs available today. In addition, practical implementation and operational challenges are discussed. We also assess the performance benefits of CoMP in these deployment scenarios with traffic varying from low to high load.]]></description>

			<link><![CDATA[http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumber=6146464&arnumber=6146496]]></link>
			<description><![CDATA[Deployment of low-power nodes such as picocells, femtocells, and relay nodes within macrocell coverage is seen as a cost-effective way to increase system capacity and to equip wireless WANs with the ability to keep up with the increasing demand for data capacity. These new types of deployments are commonly referred to as heterogeneous networks and are currently receiving significant attention in industry. However, simple deployment of low-power nodes can lead to underutilization of air-interface resources due to the relatively small footprint of the lowpower nodes or service outage in the case of femto cells with restricted access. Time-domain interference management techniques by the configuration of almost blank subframes, introduced in LTE Rel-10 standards, allow the removal of most of the interference from the dominant interfering nodes. This mechanism enables cell biasing or cell range extension of weak cells, thereby maximizing the incremental gain provided by the deployment of low-power nodes. The configuration of ABS changes the interference conditions seen by the user equipment and therefore requires corresponding resource-specific measurements and feedback at the UE. In this article, we provide an overview of LTE Rel-10 resource specific radio link monitoring, radio resource management, and channel state information feedback procedures. Also, we provide evaluation results to show that UE receivers, in the detection of weak cells and removal of interference in demodulation of control and data channels, play a critical role in realizing the full potential that the deployment of heterogeneous networks can offer.]]></description>

			<description><![CDATA[This article describes a design approach adopted in developing networking capabilities for NATO??s next generation narrowband waveform tactical radios. Providing improved link spectral efficiencies and maintaining long communication range, these new radios enable an opportunity to utilize mult-hop networking features that have been developed for mobile ad hoc networks during the past decade. The challenge, however, is to select and devise networking solutions of predictable and robust performance. For this purpose, a network-science- based approach is taken to first capture and understand the fundamental network properties exhibited when connecting tactical radios. This application of an empirical foundation has proven effective in discovering the dynamic network topological behavior and connectivity attributes. The results illustrate critical implications on the network protocol design and provide important guidance on selecting required networking solutions.]]></description>
