<p>An object of the present invention is to prevent degradation of communication quality and decrease of manageable number of mobile terminals due to interference by signal components received at different timings under channel distortion. The present invention is directed to a mobile station receiving method on a down channel in a CDMA (Code Division Multiple Access) cellular system in which a base station modulates, by using orthogonal pseudo noise sequences, transmission signals towards a plurality of mobile stations, transmits the modulated signals synchronously, while the mobile stations receive the modulated signals distorted by a plurality of radio channels of which delay times are different. The modulated signals transmitted by the base station are equalized and demodulated by using a filter of which frequency characteristics is inverse to that of the radio channels. <IMAGE></p> |
