Abstract
A receiving device includes a channel estimating section that performs a correlating process for a received reference signal in which a single carrier signal was transformed into a frequency domain signal and a pre-stored reference signal so as to obtain estimated channel values; a compensation coefficient computing section that computes compensation coefficients corresponding to residual multipath interferences based on a bit likelihood; a weight computing section that computes equalized weights based on the estimated channel values and the compensation coefficients; an equalizing filter that generates an equalized signal by equalizing process for the received signal that is the frequency domain signal based on the equalized weights; a residual interference replica generating section that generates residual multipath interference replicas based on frequency domain symbol replicas, the estimated channel values, and the equalized weights; and a subtracting section that subtracts the residual multipath interference replicas from the equalized signal.
