PROBLEM TO BE SOLVED: To realize CDMA mobile communication equipment whose power consumption can be reduced more than that of the case with rake maximum ratio synthesis where a rake circuit synthesizes signals while uniformalizing noise levels from each transmission source. SOLUTION: A searcher circuit 9 subtracts correlation value data outputted from correlation units 7, 8 each other. Finger circuits 10, 11 are respectively assigned to the results of subtraction such as negative signal level and positive signal level. Since the finger circuits 10, 11 can be assigned without causing complicated processing and increased circuit scale, useless assignment of the finger circuits is avoided so as to reduce the power consumption much more. |
