A method and apparatus processes a plurality of analog signals m a transceiver with multiple receive (Rx) antennas in a wireless communication system. By appropriate combining of the analog signals of each Rx antenna, this scheme allows a reduction in the number of the front end components, for example, filters, mixers and Analog to Digital Converter (ADC) devices Subsequently, the signals are separated digitally by virtue of their unique code. The benefits associated with this scheme are at least threefold. reduced cost, area, and power consumption of a multiple antenna terminal. Additionally, proper parameter settings increase signal to Quantization Noise Ratio (SQNR) at the ADC output.

L'invention porte sur un procédé et un appareil qui traitent une pluralité de signaux analogiques dans un émetteur-récepteur à antennes de réception multiples (Rx) dans un système de communication sans fil. Par une combinaison appropriée des signaux analogiques de chaque antenne de réception, cette technique permet une réduction du nombre des composants frontaux, par exemple des filtres, des mélangeurs et des dispositifs convertisseurs analogique-numérique (CAN). Les signaux sont ensuite séparés numériquement en vertu de leur code unique. Les avantages associés à cette technique sont au moins triples car on obtient la réduction du coût, de la zone et de la consommation d'énergie d'un terminal à antennes multiples. De plus, des réglages de paramètres appropriés augmentent un rapport signal sur bruit de quantification (SQNR) au niveau de la sortie du CAN.
