Abstract
An RF signal reception device including: a transposition device of signals of frequency fto a first intermediate frequency IF<f; a first bandpass filter centered on IF; a sampler at a frequency fs<IF; a second discrete-time filter centered on a second intermediate frequency IF=α·fs/M+fs/(M·n); a decimation device of a factor M; an analog-digital convertor to operate at a frequency fs/M; where α, n and M are strictly positive real numbers chosen such that: α<fs/(2·BW·M), and BW/2<fs/M·n), with BW: bandwidth of a channel of the received RF signals.
