PROBLEM TO BE SOLVED: To provide a spread spectrum communication equipment in which no out of synchronization is caused even when the level of a path traced by a DLL is very small and searching of paths from the beginning is not required. SOLUTION: A search device 103 for a synchronization device for receiver consists of a searching use PN generator 201 for generating a PN phase to search a path of a highest power, a searching correlation device 202 for outputting correlation value from sampling data and the PN signal, a data buffer 205 for storing the correlation value, a data buffer 205 for storing the correlation value, a path search device 200 for controlling searching of a path based on the correlation value from the data buffer, a PN generator 203 for outputting the PN signal to a DLL and data demodulation correlation device, and a DLL changeover device 204 for controlling the PN generator as a result of the path searching and selecting the PN phase into a phase of a path with a highest power. Thus, the PN phase outputted to the DLL is kept to the phase of the path with the highest power at all times. |
