Basisband-Signalprozessor von kleiner Struktur zur Kommunikations-Verarbeitung mit mehrfachen Übertragungsraten und Benutzern

摘要

A baseband signal processor is used in a base station of a CDMA communication system. The baseband signal processor comprised a plurality of processing panels which abstract specific data sequences from an input signal to produce abstracted data sequences. A RAKE section is connected to the processing panels which synthesize the abstracted data sequences to produce the synthesized data sequence. A controller is related to the processing panels and connected to the RAKE section to select at least one of the processing panels in response to a first transmission rate. Selected processing panels selected by the controller abstract the first derivative data sequences from the input signal as the specific data sequences and to produce first abstracted data sequences as the abstracted data sequences. The RAKE section synthesizes the first abstracted data sequences under the control of the controller.
