Software-based approaches enable engineers to build wireless system radios that are easier to manufacture, more flexible, and more cost-effective. <I>Software Radio: A Modern Approach to Radio Engineering</I> systematically reviews the techniques, challenges, and tradeoffs of DSP software radio design. Coverage includes constructing RF front-ends; using digital processing to overcome RF design problems; direct digital synthesis of modulated waveforms; A/D and D/A conversions; smart antennas; object-oriented software design; and choosing among DSP microprocessors, FPGAs, and ASICs. This is an excellent book for all RF and signal processing engineers building advanced wireless systems.
