Abstract
A search unit of a receiver synchronizer includes a search PN signal generator for generating PN signals for all PN phases in order to search the maximum power path; a search correlation unit which outputs a correlation value from sampling data and the PN signal; a data buffer for storing the correlation value; a path search unit for controlling a search the path using the correlation value received from the data buffer; a PN signal generator for outputting a PN signal to a DLL and a data demodulation correlation device; and a DLL switch for switching the PN phase to the phase of the maximum power path by controlling the PN signal generator as a result of the search for the path. The PN phase of the PN signal output to the DLL is constantly maintained in synchronization with the phase of the maximum power path.
