PROBLEM TO BE SOLVED: To raise the accuracies of the equalizing start timing, the equalizing range and the channel estimation in the case of many users. SOLUTION: An equalizing start timing t0, an equalizing range te and channel H estimation are made every user signal to generate received signal replicas Re<SB>1</SB>-ReN of each user. These replicas are subtracted from the received signals to take error signals Es. The replicas Re<SB>1</SB>-RnN are added to the Es to take interference-suppressed received signals of users 1-N, respectively, and t0, te, H, Re<SB>1</SB>-ReN are generated about them to further make Es. Similar steps are repeated to increase the accuracies of t0, te, H. COPYRIGHT: (C)2004,JPO
