Patent ID: 8711902

Claim:
A synchronization processing circuit in a wireless communication system, comprising: a plurality of correlation operation units mounted with a plurality of correlators which execute correlation operation, a unit which selectively switches, on said correlation operation unit basis, timing correlation processing of shifting a correlation code and transferring the shifted code between adjacent correlators in said correlation operation unit and transferring said shifted correlation code to other adjacent correlation operation unit to execute correlation operation with respect to reception data at different timing in each correlation operation unit and code correlation processing of executing correlation operation with respect to reception data at the same timing in each correlation operation unit by a correlation code individually and externally applied to each correlation operation unit, an input data control unit which transfers a desired reception data signal to said plurality of correlation operation units, and a correlation result data output selection unit which selects and arbitrates correlation result data from said plurality of correlation operation units and outputs the data to a succeeding stage unit.
