<p>PROBLEM TO BE SOLVED: To prevent deterioration in the reception quality that may contrarily be caused through the interference elimination processing for a band where the level of an interference signal is comparatively small in a receiver eliminating an interference signal from a received signal including the interference signal and a spread signal spread and modulated by the CDMA system. SOLUTION: A division means 11 divides one of two signals obtained by distributing a received signal into signals of a plurality of bands, reconfiguration means 12-14 reconfigure signals with the same bandwidth as that of the received signal maintaining signals of a level being higher than a prescribed value among the plurality of band-split division signals, a time difference means 1 provides a time difference of one chip of the spread code or over between the other signals obtained by distributing the received signal and the reconfigured signal, extract means 2, 4 extract the correlated signal components between the two signals with the time difference given by the extract means as an interference signal component and an elimination means 3 eliminates the extracted interference signal component from the received signal.</p> |
