PROBLEM TO BE SOLVED: To provide a spread spectrum communication correlator capable of reducing power consumption by decreasing a circuit scale and completely realizing a correlation calculation of a reception base band signal. SOLUTION: The spread spectrum communication correlator comprises an adder, a subtracter for adding and subtracting an in-phase component and an orthogonal component of the reception base band signal, and a phase rotator for conducting a phase rotation of output results of the adder and the subtracter based on values of a reference diffusion code of the in-phase component and the orthogonal component to output demodulated results of the respective components. Thus, the circuit scale can be reduced, the power consumption can be reduced. A correlation calculation of the reception base band signal can be completely realized. |
