Abstract:
1. An adaptive equalizing apparatus comprising: interference canceling means supplied with a received signal, a channel estimation value and an a priori information stream, for canceling an interference component in said received signal; a filter part supplied with said interference-cancelled received signal, for suppressing interference and for combining multi-path components; an interference-cancellation-degree estimation part supplied with information based on the state of iteration processing of said received signal, for estimating the degree of interference cancellation; update timing generating means supplied with at least an iteration start signal, for generating a filter coefficient update timing signal for each period during which the filter coefficients of said filter part are held unchanged; and filter coefficient calculating means supplied with the degree of interference cancellation, the channel estimation value and said update timing signal, for calculating the filter coefficients of said filter part upon each generation of said update timing signal.
