Abstract :
The stumbling blocks in development of a commercially usable software radio have been the availability of hardware, in particular the fast DSP required. As high performance ADCs have become available commercially, with the sample rates and spurious free dynamic ranges required, hybrid techniques using specialized digital hardware, operating under software control, have become more common
