Sampled Analog Signal Processing: From Software-Defined to Software Radio

摘要

This chapter has presented an overview of Software-Defined to Software Radio systems de dedicated to handsets. Technological bottlenecks were exhibited and two solutions were proposed to answer it. The first one is an intermediate frequency digitalization solution, but it is a narrow band system that locks the architecture to the Software-Defined Radio concept. A degree of reconfigurability is given by a second solution. It is a sampled analog signal processing system that allows to access to a full Software Radio architecture. This disruptive system opens researches to a new kind of radio architectures.
