Synchronization processing circuit and synchronization processing method in wireless communication system

A synchronization processing circuit in a wireless communication system, comprising

• a plurality of correlation operation units which execute correlation operation, wherein said correlation operation unit comprises
• a plurality of correlators,
• a plurality of shift units which shift a correlation code,
• an interface which transfers said correlation code shifted to an adjacent correlation operation unit for timing correlation processing,
• a first correlation code selection unit which selects an externally and individually applied correlation code for code correlation processing and a correlation code transferred from an adjacent correlation operation unit as said correlation code,
• 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.

A synchronization processing method of a synchronization processing circuit in a wireless communication system, wherein

• in a plurality of correlation operation units mounted with a plurality of correlators which execute correlation operation,
• selectively switching, 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 step of transferring a desired reception data signal to said plurality of correlation operation units, and
• a correlation result data output selecting step of selecting and arbitrating correlation result data from said plurality of correlation operation units and outputting the selected data to a succeeding stage device.
