Abstract
-Baptiste Begueret, Dominique Dallet , Member , IEEE, Philippe Cathelin, and Didier Belot , Senior Member , IEEE Abstract—Many technological bottlenecks prevent from re- alizing a software radio (SR) mobile terminal. The old way of building radio architectures is now over because a single handled terminal has to address various communication standards. This paper exposes a SR receiver: a sampled analog signal processor (SASP) is designed to perform downconversion and channel presorting. The idea
