Software Defined Radio by Markus Dillinger,Kambiz Madani,Nancy Alonistioti Pdf
Software defined radio (SDR) is a hot topic in the telecommunications field, with regard to wireless technology. It is one of the most important topics of research in the area of mobile and personal communications. SDR is viewed as the enabler of global roaming and a platform for the introduction of new technologies and services into existing live networks. It therefore gives networks a greater flexibility into mobile communications. It bridges the inter-disciplinary gap in the field as SDR covers two areas of development, namely software development and digital signal processing and the internet. It extends well beyond the simple re-configuration of air interface parameters to cover the whole system from the network to service creation and application development. Reconfigurability entails the pervasive use of software reconfiguration, empowering upgrades or patching of any element of the network and of the services and applications running on it. It cuts across the types of bearer radio systems (Paging to cellular, wireless local area network to microwave, terrestrial to satellite, personal communications to broadcasting) enable the integration of many of today's disparate systems in the same hardware platform. Also it cuts across generation (second to third to fourth). This volume complements the already published volumes 1 and 2 of the Wiley Series in Software Radio. The book discusses the requirements for reconfigurability and then introduces network architectures and functions for reconfigurable terminals. Finally it deals with reconfiguration in the network. The book also provides a comprehensive view on reconfigurability in three very active research projects as CAST, MOBIVAS and TRUST/SCOUT. Key features include: Presents new research in wireless communications Summarises the results of an extensive research program on software defined radios in Europe Provides a comprehensive view on reconfigurability in three very active research projects as CAST (Configurable radio with Advanced Sodftware Technology), MOBIVAS (Downloadable MOBIle Value Added Services through Software Radio and Switching Integrated Platforms), TRUST (Transparently Re-configurable Ubiquitous Terminal) and SCOUT (Smart User-Centric Communciation Environment).
Software Defined Radio by John Bard,Vincent J. Kovarik, Jr Pdf
The Software Communications Architecture (SCA) establishes an implementation-independent framework for the development of Joint Tactical Radio System software configurable radios.

Next-generation mobile communications are likely to employ different techniques and standards. The implementation in software of as many receiver functionalities as possible appears to be the most effective solution for coping with the multiplicity of communications alternatives. The concept of software radio, dating back to 1991, originally attracted commercial interest owing to the possibility that transmission layer functions could be fully software-defined. The same approach can be extended to protocols of the higher layers too, thus conceiving a programmable hardware to implement the functionalities of several layers of protocols by resident software or software downloaded from the network. Consisting of selected technical contributions to the Workshop on "Software Radio", this volume deals with state-of-the-art surveys of the enabling technologies and the prospective services of software radio implementations for future mobile communications. Original and state-of-the-art research and development is presented in fields such as: - Software radio for universal wireless internet access - Software radio for multimedia communications - Software radio architecture - Network architecture, protocols and services - Software radio technology towards pervasive appliance. This volume on software radio is a valuable reference for both researchers and telecommunications professionals.

Cognitive networks can dynamically adapt their operational parameters in response to user needs or changing environmental conditions. They can learn from these adaptations and exploit knowledge to make future decisions. Cognitive networks are the future, and they are needed simply because they enable users to focus on things other than configuring and managing networks. Without cognitive networks, the pervasive computing vision calls for every consumer to be a network technician. The applications of cognitive networks enable the vision of pervasive computing, seamless mobility, ad-hoc networks, and dynamic spectrum allocation, among others. In detail, the authors describe the main features of cognitive networks clearly indicating that cognitive network design can be applied to any type of network, being fixed or wireless. They explain why cognitive networks promise better protection against security attacks and network intruders and how such networks will benefit the service operator as well as the consumer. Cognitive Networks Explores the state-of-the-art in cognitive networks, compiling a roadmap to future research. Covers the topic of cognitive radio including semantic aspects. Presents hot topics such as biologically-inspired networking, autonomic networking, and adaptive networking. Introduces the applications of machine learning and distributed reasoning to cognitive networks. Addresses cross-layer design and optimization. Discusses security and intrusion detection in cognitive networks. Cognitive Networks is essential reading for advanced students, researchers, as well as practitioners interested in cognitive & wireless networks, pervasive computing, distributed learning, seamless mobility, and self-governed networks. With forewords by Joseph Mitola III as well as Sudhir Dixit.

Computing Platforms for Software-Defined Radio by Jari Nurmi,Jouni Isoaho,Fabio Garzia Pdf
Software-Defined Radio (SDR) has been a hot topic both in academic and industrial research already for several years, yet no final definite solution to the implementation architecture for it has emerged. As SDR is a key enabling technology for taking the next step, implementing a true Cognitive Radio, it is high time to overview and discuss the proposals for SDR architecture. The computing platforms for SDR have not been addressed thoroughly and holistically in the literature by now. There are a few books that analyse from a theoretical point of view algorithms, software and hardware techniques to implement SDRs, but a clear point of reference for computer architects is missing. The approaches in this book can be divided into three main categories: 1) Architectures exploiting parallelism by extending single-processor environment (such as VLIW, SIMD, TTA approaches); 2) Multi-core platforms distributing the computation to either a homogeneous array or a set of specialized heterogeneous processors; and 3) Reconfigurable architectures exploiting fine-grain, coarse-grain, or hybrid reconfigurability.
