Multi-standard applications encounter several developments in the wireless systems. A single receiver is required for any standard of communication. Software Radio (SR) is an illustration of this concept. This paper presents a design methodology to ease the design of a flexible RF receiver based on an analog discrete time Fast Fourier Transform (FFT). A proposed architecture named SASP (Sampled Analog...
This paper presents the principles of a Sampled Analog Signal Processor (SASP) dedicated to software radio mobile device. Many technological bottlenecks are to be overcome. The idea is to design a discrete analog signal processor to challenge theses bottlenecks. The main issue associated with the A/D conversion is thus avoided. The SASP aims to select a spectral envelope of a RF signal among all RF...
The RF transceivers architectures are to integrate the concept of software radio. But, in the case of mobile terminal, hard constraints are imposed by the factor of mobility. Low power and very complex circuits are claimed by the telecommunication industry. Classical architectures are no more sufficient to challenge this goal. New systems are thus proposed, and the concept of software defined radio...
