PROBLEM TO BE SOLVED: To properly detect a valid path even when a PN code of a non-M sequence is used as a spread code and an inverse spread code. SOLUTION: An autocorrelation detection section 28 detects autocorrelation in a PN code and transmits time information of a sub peak in excess of a prescribed threshold to a valid path detection section 32 via a control section 36. The valid path detection section 32 excludes a path corresponding to the time information from valid paths to detect the resulting valid paths. Or the autocorrelation detection section 28 transmits the time information and information denoting a rate of the sub peak to the main peak in the autocorrelation and the valid path detection section 32 subtracts the correlation power of a corresponding delay time with respect to the correlation power of the direct path by its ratio to correct the delay profile. |
