<p>A DS-CDMA (Direct Sequence-Code Division Multiple Access) multi-user interference canceller is provided with a notifying unit for notifying symbol information, a delay of each path and transmission estimation value information of each path to other users, a correlation value calculator for calculating cross correlation values with spread code sequences of the other users in each user in advance, an interference calculator for calculating interference components of the other users on the basis of the information notified by the other users and the cross correlation values calculated in advance, and a subtracter for subtracting the interference components from the signal component of the present user, whereby the interference components are generated and cancelled at a symbol rate after a reception signal is subjected to despread.</p> |
