Software-defined radio (SDR): High-impact Technology - What You Need to Know: Definitions, Adoptions, Impact, Benefits, Maturity, Vendors,
A software-defined radio system, or SDR, is a radio communication system where components that have been typically implemented in hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a personal computer or embedded computing devices. While the concept of SDR is not new, the rapidly evolving capabilities of digital electronics render practical many processes which used to be only theoretically possible. A basic SDR system may consist of a personal computer equipped with a sound card, or other analog-to-digital converter, preceded by some form of RF front end. Significant amounts of signal processing are handed over to the general-purpose processor, rather than being done in special-purpose hardware. Such a design produces a radio which can receive and transmit widely different radio protocols (sometimes referred to as a waveforms) based solely on the sof tware used. Software radios have significant utility for the military and cell phone services, both of which must serve a wide variety of changing radio protocols in real time. In the long term, software-defined radios are expected by proponents like the SDRForum (now The Wireless Innovation Forum) to become the dominant technology in radio communications. SDRs, along with software defined antennas are the enablers of the cognitive radio. This book is your ultimate resource for Software-defined radio (SDR). Here you will find the most up-to-date information, analysis, background and everything you need to know. In easy to read chapters, with extensive references and links to get you to know all there is to know about Software-defined radio (SDR) right away, covering: Software-defined radio, 2G, 3G, 4G, Digital Enhanced Cordless Telecommunications, GNU Radio, HPSDR, List of software-defined radios, Orthogonal frequency-division multiplexing, Software GNSS Receiver, SpeakEasy, Universal Software Radio Peripheral, Multiplexing, Circuit switching, Time-division multiplexing, Frequency-division multiplexing, Multi-user MIMO, Polarization (waves), Spatial multiplexing, Statistical time division multiplexing, Packet switching, Time division multiple access, Frequency-hopping spread spectrum, Direct-sequence spread spectrum, Orthogonal frequency-division multiple access, Single-carrier FDMA, Multi-carrier code division multiple access, Channel access method, Media Access Control, Modulation, Amplitude modulation, Single-sideband modulation, Quadrature amplitude modulation, Frequency modulation, Phase modulation, Space modulation, Frequency-shift keying, Multiple frequency-shift keying, Amplitude-shift keying, On-off keying, Phase-shift keying, Minimum-shift keying, Continuous phase modulation, Pulse-position modulation, Trellis modulation, Spread spectrum, Chirp spread spectrum, Time-hopping, Demodulation, Modem, Line code, Pulse-amplitude modulation, Pulse-width modulation, Pulse-code modulation This book explains in-depth the real drivers and workings of Software-defined radio (SDR). It reduces the risk of your technology, time and resources investment decisions by enabling you to compare your understanding of Software-defined radio (SDR) with the objectivity of experienced professionals.

Wireless Personal Communications,Advances in Coverage and Capacity
The wireless industry is growing at a phenomenal rate. Cellular subscribers are increasing at a rate of 45% per year, the market for wireless local loop service is growing at a rate of 42%, and the wireless local area network market is growing at a rate of 61 %. This growth and potential for future growth has motivated companies to commit $20 billion in obtaining 90 MHz of PCS spectrum during the recent FCC auctions in the United States. Obviously spectrum is a costly, but critical, resource. Efficient utilization of this resource is essential for profitable wireless service. To meet this challenge, researchers in wireless communications are tenaciously developing more spectrally efficient modulation techniques, planning tools for efficient communication system layout, and digital signal processing techniques for more robust communications. The papers and lectures presented in this book were originally given at the Sixth Annual Virginia Tech Symposium on Wireless Personal Communications and cover a broad range of topics in wireless communications. The majority of the papers are relevant to creating higher capacity (spectrally efficient) systems with greater coverage. Topics include adaptive antenna array measurements and algorithm comparisons, Cellular Digital Packet Data deployment guidelines, speech coding techniques, wireless system design methodology, and propagation measurements in hostile or previously unexplored channels.
