PROBLEM TO BE SOLVED: To provide a method for reversely diffusing and a reverse diffusing circuit capable of achieving an optimum performance in a hardware having no idle in various propagation environments by commonly using a correlator for a searcher and a correlator for a finger. SOLUTION: The correlators (300-1) to (300-i) are commonly used for the searcher and the finger. A selecting circuit 40 decides a number of the correlators for sharing a calculation of a first correlated value and a number of the correlators for sharing a calculation of a second correlated value in response to an amount and a quality of a reception signal. A replica signal sent from a replica generator 11 is output to the prescribed number of the correlators used as the searcher. A signal obtained by delaying a diffusion code generated from a code generator 21 by a delay circuit 22 is output to the prescribed number of the correlators used as the finger. |
