Towards Software Radio Receiver

Résumé

Many technological bottlenecks prevent from realizing 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 presentation exposes a SR receiver: a Sampled Analog Signal Processor (SASP) is designed to perform downconversion and channel presorting. The idea is to process analog voltage samples in order to recover in baseband any RF signal emitted from 0 to 5GHz. An analog Fast Fourier Transform achieves both frequency shifting and filtering. An experimental demonstrator of the SASP using 65nm CMOS technology from STMicroelectronics is here presented and measured. It validates the concept of a new SR receiver with the design of a demonstrator which runs at 1.2GHz consuming 389mW. Further works are proposed: a DVB-S receiver using SASP technology is exhibited and an application to Cognitive Radio is presented.
