Radio-frequency signals received by two antennas are respectively amplified by two amplifiers. Of the two signals, only the radio-frequency signal received by the second antenna is delayed by a delay time T through a delay circuit. The output from the delay circuit and the output from the first amplifier connected to the first antenna are combined by a combiner. From this stage toward subsequent stages, a shared receiver lowers the frequency of the combined signal to that of a base band signal, which is converted into a digital signal by a shared A/D converter. This digital signal is demodulated by a Rake receiver, and the demodulated result is decoded by the decoder to reproduce transmitted data.

L'invention concerne des signaux radioélectriques, reçus par deux antennes, qui sont amplifiés respectivement par deux amplificateurs. Des deux signaux, seul le signal radioélectrique reçu par la seconde antenne est retardé d'un temps de délai T au moyen d'un circuit à retard. La sortie du circuit à retard et la sortie du premier amplificateur relié à la première antenne sont combinées par un combinateur. De cette étape jusqu'aux étapes subséquentes, un récepteur partagé abaisse la fréquence du signal combiné à celle d'un signal en bande de base, qui est converti en signal digital au moyen d'un convertisseur analogique numérique partagé. Ce signal digital est démodulé par un récepteur Rake, et le résultat de la démodulation est décodé par le décodeur afin de reproduire les données transmises.
