International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / Digital signal processing has inexorably been woven into the fabric of every function performed in a modern radio communication system. In the rush to the marketplace, we have fielded many DSP designs based on analog prototype solutions containing legacy compromises appropriate for the technology of a time past. As we design the next generation radio we pause to examine and review past solutions to past radio problems. In this review we discover a number of DSP design methods and perspectives that lead to cost and performance advantages for use in the next generation radio.
