Patent ID: 8000352

Claim:
A synchronizer for both a communication device and an access point comprises: the synchronizer being installed inside the communication device; a coefficient generator generating a set of coefficient code; a parallel-to-serial converter receiving a set of input code from an access point, performing a parallel-to-serial conversion on said set of input code and outputting a result; a coefficient element array including a plurality of coefficient elements interconnecting with each other, wherein each of said coefficient elements receives said set of input code from said parallel-to-serial converter and receives said set of coefficient code, and then performs a passive correlation operation or an active correlation operation on said set of input code and said set of coefficient code to output a correlation value to said access point for synchronizing signals of said communication device and said access point; said coefficient element array is a square matrix containing 16×16 pieces of coefficient elements; each row of said coefficient element array has 16 pieces of said coefficient elements connected in series, and said coefficient element array totally has 16 rows; each row of said coefficient element array is connected to a first multiplexer; and said first multiplexer receives correlation values output by 16 pieces of said coefficient elements of one row of said coefficient element array and selects one of said correlation values to output.
