PROBLEM TO BE SOLVED: To improve the receiving quality in a spread spectrum receiver. SOLUTION: A signal is correlated in a pseudo-noise code correlation calculating section 10 by using a pseudo-noise code and the phase shift quantity is calculated in a prescribed time from this signal by delay processing sections 16 and 17, multiplying sections 18 and 19, and a difference calculating section 20 to generate frequency error information for each data decoding section 4-1, 4-2 through 4-n. Base station information corresponding to the signals received by the sections 4-1, 4-2 through 4-n is outputted from a phase searching processing section 31, frequency error information is integrated for each base station by a frequency error integrating section 32 by base stations, and the frequency is controlled so as to follow the frequency of a prescribed base station. |
