SYNCHRONIZATION CAPTURE METHOD, SYNCHRONIZATION CAPTURE CIRCUIT AND WIRELESS COMMUNICATION SYSTEM

摘要

A synchronization capture circuit (11) is provided to each wireless communication station (10), and has the following: a matched filter bank (111) that outputs a first correlation value that is a correlation value between a wireless signal received from a synchronization control station (12) and another wireless communication station (10), and a sequence of spread codes used in a synchronization signal, and that outputs a plurality of second correlation values that are correlation values between the received wireless signal and each sequence of spread codes used in each data signal; and an absolute value addition circuit (112) that calculates the sum of the absolute values of the plurality of second correlation values. A synchronization signal is detected on the basis of the sum of the absolute values of the first correlation value and the plurality of second correlation values.
