Patent ID: 7248619

Claim:
A rake receiver in a CDMA mobile communication system, characterized by comprising: a correlation-value calculation section for calculating correlation values between reception signals and spreading codes at all timings at which rake reception is possible; a delayed-profile creation section for creating a delayed profile by determining an average correlation value from the correlation values for each reception timing, the correlation values being obtained from the correlation-value calculation section; a difference-history creation section for creating a difference history by comparing the latest correlation value issued from the correlation-value calculation section with a previous correlation value for each reception timing; a path selection section for rearranging the average correlation values in decreasing order, selecting a reception timing to be assigned to a finger in decreasing order of the average correlation values when the delayed profile and the difference history satisfy respective predetermined conditions, and issuing the reception timing to a finger section; and the finger section for performing reception corresponding to a path for each reception timing.
