28 October 1998: Processing Trends and Challenges in Wireless Communications Mark Cummings, Managing Director Advanced Technology Development Cadence Wireless Design Services, Chairman, enVia Inc. A brief historical perspective of the evolution of the application of digital technologies provides the context for a discussion of directions for solutions to the current technical challenges in high speed signal processing required to support SDR (Software Defined Radio) baseband processing. Strengths and weaknesses of various approaches will be considered including multiple ASIC chip sets, parameterized ASICS, switchable microcode processors, high speed DSP's, reconfigurable logic, and VLIW. The discussion will conclude with consideration of the areas of technical challenge that will be encountered after baseband solutions are stable.
