摘要： By calculating the complex product between each of the complex conjugate pattern for the pilot patterns assigned individually to a plurality of transmitting antennas of a base station and de-spread signals (ISI, ISQ), which have been obtained from a received signal by de-spreading portion (22), a separating section (23) separates the pilot block of the de-spread signals, for each of the plurality of transmitting antennas, from the received signal. Subsequently, after a delay profile for the transmitted signal from each of the plurality of transmitting antennas is generated by using the separated signals (PLI 1 , PLQ 1 ), (PLI 2 , PLQ 2 ), a delay profile combining portion (27) combines into a delay-profile for multi-path selection, and multi-path selection is performed based on the delay profile for multi-path selection. Therefore, highly accurate path search is possible in a DS-CDMA system that employs a transmitter diversity scheme.
