The present invention relates to a receiver for processing a received signal (SEQ), said receiver being multimode. The invention is characterized in that it comprises; a) a single RF chip for processing the received signal (SEQ) in any mode, said chip comprising a spreading section (SPREAD SEC) for spreading and downconverting to baseband a received signal (SEQ), and a channel filtering section (CH SEC) for DC offsets rejection on a received signal (SEQ), and b) a single baseband chip (BB) comprising despreading means (DSPR) for despreading a spread signal (SEQ).
