| description | A receiver (100), transmitter (200) and transceiver (400) in accordance with the present invention overcome the disadvantages of applying adaptive antenna array technology to multi-channel communication systems. Multi-channel radio frequency (RF) signals received via an adaptive antenna array (102) are converted from an analog form to a digital form prior to splitting and processing to recover communication channels contained therein. A number of digital communication signals are digitally combined into a multi-channel digital signal and converted from the digital form to an analog radio frequency form prior to transmission from the adaptive antenna array.
Un récepteur (100), un émetteur (200) et un émetteur-récepteur selon l'invention viennent à bout des inconvénients de l'utilisation d'une technologie faisant intervenir une antenne auto-adaptative dans un système de télécommunications à multi-canaux. Des signaux de fréquence radioélectrique (RF) multi-canaux reçus par un réseau d'antennes auto-adaptatives (102) sont convertis de la forme analogique à la forme numérisée avant fractionnement et traitement pour recouvrer des canaux de communications qu'ils contiennent. Un certain nombre de signaux de communication numérisés sont combinés de manière numérique en un signal numérique multi-canaux et convertis de la forme numérique à une forme analogique de fréquence radioélectrique avant une émission à partir du réseau d'antennes auto-adaptative. |
