Survey of Full Software Radio Transceivers
Résumé
This talk addresses the current status and trends in research on Full Software Radio (FSR) systems. Concerning the receiver path after defining Software Defined Radio (SDR) versus FSR a new version of the Sampled Analog Signal Processor (SASP) is presented and experimental results are discussed. The new version doubles the signal bandwidth of the initial prototype while the power consumption is reduced to less than 100 mW. For the transmitter path, two new FSR architectures are presented based on Riemann's algorithm and a charge pump (namely the Riemann's Pump), first, and a Fourier recombination transmitter (FoRTX) in nanoscale CMOS, second. A GaN demonstrator of the Riemann's Pump is presented, which generates any signal including concurrent emissions in the 0-to-1 GHz band, and a 28nm SOI CMOS FoRTX is presented as well addressing roughly the same frequency band.
