Résumé
Abstract

Nous présentons dans cet article l'architecture d'un récepteur radio reconfigurable pour applications mutistandards. Le récepteur est basé sur l'échantillonnage en bande RF et sur un traitement de signal analogique à temps discret. Des opérations de filtrage anti-repliement, de translation en fréquences par sous échantillonnage, de filtrage canal et de décimation sont effectuées le long de la chaîne. En ajustant la fréquence d'échantillonnage, il est possible de translater toutes ces opérations d'une bande RF à une autre et d'adresser ainsi la plupart des standards de communication actuels.

This article presents the architecture of a reconfigurable radio receiver intended for multistandard applications. The receiver is based on RF sampling and discrete time analog signal processing. Anti-alias filtering, downconversion by bandpass sampling, channel selection filtering and sampling rate decimation are performed throughout the receiver chain. By adjusting the input sampling rate, all these operations can be tuned to different RF bands. This achieves full system reconfigurability and allows us to cover most of the existing communication standards.
