(EN) RADIO COMMUNICATION SYSTEM, RECEIVER AND TRANSMITTER
(FR) SYSTEME DE RADIOCOMMUNICATION, RECEPTEUR ET EMETTEUR
Abstract
(EN) The present invention discloses a receiver of a radio communications system, comprising: a plurality of antennas for receiving RF signals; a plurality of oscillators for providing different oscillating frequencies; a plurality of IF signal generators respectively connected to the oscillators, for converting RF signals to obtain IF signals; a combiner for combining the signals outputted from the IF signal generators; and a baseband signal generators, for converting the combined signal to obtain a baseband signal. According to the present invention, the cost and power consumption can be largely reduced.
(FR) La présente invention concerne un récepteur d'un système de radiocommunication, comprenant : une pluralité d'antennes destinées à la réception de signaux RF ; une pluralité d'oscillateurs fournissant des fréquences d'oscillation différentes ; une pluralité de générateurs de signaux IF connectés respectivement aux oscillateurs, destinés à la conversion des signaux RF en signaux IF ; un coupleur destiné au couplage des signaux produits par les générateurs de signaux IF ; et des générateurs de signaux de bande de base, destinés à la conversion du signal couplé en signal de bande de base. Selon la présente invention, ce récepteur permet de réduire sensiblement les coûts et la consommation.
