CA 2206311

A wideband multi-channel transmitter and receiver (transceiver) for cellular communication systems. The transceiver includes programmable digital down converters (DDCs) and programmable digital up converters (DUCs) providing a range of decimation/interpolation ratios to accommodate multiple access, i.e. AMPS, NAMPS, USDC, PDC, for varying signal formats and bandwidths. The method of digitizing a wideband frequency signal used by DDCs and DUCs has application to digitizing any wideband signal occupying continuous or discontinuous spectrum while reducing sampling frequency and hardware requirements. The arrangement of elements in the transceiver allows channel processing functions to be performed centrally, and transceiver functions to be performed at a communication cell site. The result is a savings to the operator by way of physical space required for equipment and in more centralized operation and maintenance activities.

Récepteur (200) et émetteur (300) numériques, le récepteur numérique comprenant une pluralité d'antennes (202) conçues pour recevoir des signaux de fréquence de la liaison montante; une pluralité de convertisseurs analogique/numérique (210) conçus pour convertir les signaux de radiofréquence reçus en signaux numériques; un abaisseur de fréquence commuté (214) conçu pour abaisser la fréquence d'un des signaux numériques et le convertir en un signal FI dans la bande de base; et un processeur de voies (228) conçu pour récupérer une des voies de communication multiples contenues dans le signal FI dans la bande de base.
