ABSTRACT:
A spread spectrum receiving apparatus is constructed by a generator for generating a reference clock, a phase shift circuit for shifting the phase of the reference clock generated by the generator in accordance with a code timing in a reception signal and the reference clock, and a de-spreading circuit for de-spreading the reception signal in accordance with the reference clock whose phase is shifted by the phase shift circuit. The de-spreading circuit generates a code for de-spreading in accordance with the phase shifted reference clock. The phase shift circuit has a calculator for calculating a phase shift amount so as to synchronize the code timing in the reception signal with the code for reception in accordance with a deviation between the code timing in the reception signal and the reference clock.
