In a rake receiver, a correlation-value calculation section calculates correlation values between spreading codes and reception signals from an input terminal and outputs the calculated correlation values to a delayed-profile creation section and a difference-history creation section. The delayed-profile creation section determines average correlation values and issues the values as a delayed profile to a path selection section. For each reception timing, the difference-history creation section compares the latest correlation value with a previous correlation value held by the difference-history creation section, to determine a difference history, and issues the difference history to the path selection section. The path selection section rearranges the delayed profile in decreasing order of the average correlation values. When the delayed profile and the difference history satisfy all predetermined conditions, the path selection section assigns the corresponding reception timing to a finger and issues the reception timing to the finger section.
