PROBLEM TO BE SOLVED: To provide a spread spectrum signal processor suitable for a communication using an analog correlator of small size which can be mounted on portable equipment for a spread spectrum communication using long spread codes. SOLUTION: This system has a correlator 10 which correlates a spread spectrum signal and a supplied reference signal with each other, an A/D converter 40 which converts a correlation signal to a digital signal, a memory 50 which stores the digital signal from the A/D converter 40 as digital data, a signal processor 60 which adds digital data corresponding to code sequences C1 to C16 respectively and outputs the corresponding addition result, and a controller 70 which performs control for supplying the code sequences C1 to C16 as the reference signal to the correlator 10 repeatedly in the order, and the signal processor 60 starts the adding process by referring to the timing signal from the controller 70. |
