<p>PROBLEM TO BE SOLVED: To provide a receiver capable of executing communication high in quality by correcting the phase shift of an estimated transmission path characteristic, then executing averaging and generating a correction signal while considering the phase shift of the reception signal. SOLUTION: Inverse diffusion is executed with diffused codes corresponding to respective units and plural reception signals different in arrival time are extracted. The frequency offsets of the plural reception signals are estimated. Correction signals corresponding to the respective reception signals are generated from the plural reception signals and estimated frequency offsets. The reception signals corresponding to respective paths after correction by the highly precise correction signals are synthesized. In the receiver, a frequency offset estimation circuit 2 calculates the estimated frequency offset based on the reception signals extracted by a received signal extraction circuit 1. A correction signal generation circuit 3 calculates the correction signal against the reception signal based on the reception signal extracted by the received signal extraction circuit 1 and the estimated frequency offset estimated in the frequency offset estimation circuit 2.</p> |
