Software Radio has come a long way in the last 15 years. This Tech Briefing discussed where we have come from, where we are today, and where we’re going in the future, highlighting what previously has and has not worked, and what challenges still remain.
Specific topics covered included:
- Challenges in hardware for Software Radio, and a discussion of the state of the art in RF frontends and data converters
- The evolution of the various processing paradigms used in software radio (GPP, GPU, DSP, and FPGA)
- What problems we thought would be solved by now
- The basic economics of software radios in volume production
