DEVICE AND METHOD FOR RECEIVING RF SIGNALS BASED ON HETERODYNE ARCHITECTURE USING COMPLEX IF SUBSAMPLING |
| 摘要 |
An RF signal reception device including: a transposition device of signals of frequency fRF to a first intermediate frequency IF1<fRF; a first bandpass filter centered on IF1; a sampler at a frequency fs<IF1; a second discrete-time filter centered on a second intermediate frequency IF2=α·fs/M+fs/(M·n); a decimation device of a factor M; an analog-digital convertor to operate at a frequency fs/M; whereα, n and M are strictly positive real numbers chosen such that:α<fs/(2·BWch·M), and BWch/2<fs/M·n), with BWch: bandwidth of a channel of the received RF signals.
