PROBLEM TO BE SOLVED: To provide a signal receiver in a DS-CDMA system, whose receiving performance is more improved by removing interferences due to the interrelation of multi-paths at a high rate. SOLUTION: An impulse response, corresponding to K pieces (K is an integer which is 2 or more) of paths, is estimated from a reception signal, and a path P capable of maximizing a power is selected based on the impulse response. Then, a plurality of inverse diffusion signal obtained by performing inverse diffusion, based on the path P are synthesized by an Rake part 102 and an interference canceller 104-1 or 104-M, so that final data can be generated. |
