    There is a great need for information technologies for developing and delivering quality, up-to-date educational materials that convey to all learners that knowledge is a dynamic continuum that stretches across disciplines. To address this need, an experimental, open-source/open-content initiative, called the Connexions Project, was initiated. The Connexions Project offers an alternative to the wa...

    Call admission control (CAC) is a mechanism used in networks to administer quality of service (QoS). Whereas the CAC problem in time-division multiple access (TDMA)-based cellular networks is simply related to the number of physical channels available in the network, it is strongly related to the physical layer performance in code-division multiple access (CDMA) networks since the multi-access int...

    The publication of Floyd and Jacobson's seminal paper "Random early detection gateways for congestion avoidance" (1993), marked a new direction in networking research and began what is perhaps the most investigated example of cross-layer optimization. While this paper has inspired an immense amount of work in research, many open problems in active queue management (AQM) still remain. This article ... View full abstract»

    This article reviewed the various aspects of MAC-PHY cross-layer designs, with the goals of introducing pertinent queuing and stability analysis tools to the SP-oriented readership, and illustrating the advantages of such cross-layer designs using the recently introduced class of xNDMA protocols as an example. The results of queuing analysis show that a jointly designed MAC-PHY layer provides incr... View full abstract»

    In this paper, a new OFDM-based air interface technology for a mobile broadband wireless system is described. The technology leverages the standard Internet protocol (IP) network elements to build the system and deploys a new air interface technology based on OFDMA. Cross-layer optimization played a major role in the design where the choices made in the physical, MAC, and link layers are also driv... View full abstract»

    A fundamental problem in networking is the allocation of limited resources among the users of the network. In a traditional layered network architecture, the resource to be allocated at the medium access control (MAC) and network layers utilizes communication links, viewed as "bit pipes" that deliver data at a fixed rate with occasional random errors. Though this separation has many advantages, th... View full abstract»

    In this paper, a cross-layer view for roles of signal processing in random access network and vice versa is presented. The two cases where cross-layer design has a quantifiable impact on system performance are discussed. The first case is a small network (such as wireless LAN) where a few nodes with bursty arrivals communicate with an access point. The design objective is to achieve the highest th...

    Direct digital synthesis (DDS) is a useful tool for generating periodic waveforms. In this two-part article, the basic idea of this synthesis technique is presented and then focused on the quality of the sinewave a DDS can create, introducing the SFDR quality parameter. Next effective methods to increase the SFDR are presented through sinewave approximations, hardware schemes such as dithering and... View full abstract»
