ABSTRACT:
The accuracy of an equalization start timing, an equalization duration and a channel estimation is improved in an application including an increased number of users. An equalization start timing t0,an equalization duration te and channel H estimation are performed for each user signal, and using these, received signal replicas Re1ro ReNfor the respective users are generated. The replicas are subtracted from the received signal to provide an error signal, and Re1to ReNare added to Es to provide an interference suppressed received signals for the users1to N. to, te, H and Re1to ReNare generated from these to generate Es in a repeated fashion to improve the accuracy of t0,te and H.
