<p>If an interference elimination unit provided to each user judges that there is no demodulation error, a replica signal calculated by the interference elimination unit is subtracted from an input signal vector, and the user signal calculated is outputted as it is as a final user signal. If the interference elimination unit judges that there is a demodulation error, the user signal is calculated again by an interference elimination unit of an interference canceler at the next stage. By thus inhibiting the subtraction of the replica signal corresponding to the user signal involving a demodulation error from the input signal vector, it is possible to enhance the precision of the interference elimination.</p> |
