    Signal processing and coding technology for digital magnetic recording is the core technology of the channel electronics module in a hard disk drive (HDD) that processes signals read from magnetic media. In this historical review I focus on what is now widely known as partial-response, maximum-likelihood (PRML) technology, which takes advantage of the inherent redundancy that exists in signals rea...

    In past issues of the column there have been articles about European Commission (EC) funded programs and also national programs (e.g., in Spain), both focusing on services and applications. In order to provide a holistic view of European programs, there is an important missing piece: the so-called Eureka program that is jointly funded by 41 countries. Within Eureka the cluster devoted to telecommu... View full abstract»

    To date, photonic integration has seen only limited use in a few optical interface applications. The recently adopted IEEE draft standards for 40 Gb/s and 100 Gb/s Ethernet single-mode fiber local area network applications will change this situation. Although first generation implementations will use discrete components based on existing technologies, long-term requirements for significant reducti... View full abstract»

    Next-generation access networks must provide bandwidths in the range of 50-100 Mb/s per residential customer. Today, most broadband services are provided through copper-based VDSL or fiber-based GPON/EPON solutions. Candidates for next-generation broadband access networks include several variants of WDM-PONs. The total cost of ownership of these solutions is determined mainly by operational expend...

    Carrier-grade Ethernet is the latest step in the three-decade development of Ethernet. This work describes the evolution of Ethernet technology from LAN toward a carrier-grade operation through an overview of recent enhancements. After reviewing native Ethernet and its transport shortcomings, we introduce the major carrier-grade upgrades. We first discuss the evolution of layer-2 architectures. Th... View full abstract»

    Dynamic bandwidth allocation in passive optical networks presents a key issue for providing efficient and fair utilization of the PON upstream bandwidth while supporting the QoS requirements of different traffic classes. In this article we compare the typical characteristics of DBA, such as bandwidth utilization, delay, and jitter at different traffic loads, within the two major standards for PONs...

    Most of the consideration of the benefits and applicability of dynamic spectrum access has been focused on opportunities associated with spectrum availability. This article describes the use of DSA to resolve challenges in achieving wireless and cognitive radio operation in dense or energetic spectrum. It also demonstrates that the use of DSA can significantly reduce requirements for linearity and... View full abstract»

  • Primary user behavior in cellular networks and implications for dynamic spectrum access

    Dynamic spectrum access approaches, which propose to opportunistically use underutilized portions of licensed wireless spectrum such as cellular bands, are increasingly being seen as a way to alleviate spectrum scarcity. However, before DSA approaches can be enabled, it is important that we understand the dynamics of spectrum usage in licensed bands. Our focus in this article is the cellular band....

  • A technical framework for light- handed regulation of cognitive radios

    Light-handed regulation is discussed often in policy circles, but what it should mean technically has always been a bit vague. For cognitive radios to succeed in reducing the regulatory overhead, this has to change. For us, light-handed regulation means minimizing the mandates to be met at radio certification and relying instead on incentives to deter bad behavior. We put forth a specific technica...

    The dynamic-spectrum-access research and development community is maturing technologies that will enable radios to share RF spectrum much more intensively. The adoption of DSA technologies by the public-safety community can better align systems with the future of wireless services, in general, and can contribute to making next-generation public-safety radio systems more robust, capable, and flexib...

  • Licensed or unlicensed: The economic considerations in incremental spectrum allocations

    At present, no existing market mechanism allows for the trading of radio spectrum between licensed and unlicensed uses. Whenever spectrum is made available for reallocation, the FCC faces a dilemma in determining which access regime to use. For example, the television white spaces are largely unused and available for reallocation. Since both licensed and unlicensed allocations are valuable, alloca... View full abstract»
