Path search system and path search method, and mobile terminal

摘要

Can be calculated with each complex conjugate patterns of pilot patterns each allocated individually multiple transmit antennas of the base station, a complex product (ISI, ISQ) of the despread signal of the reception signal obtained by despreading section 22 by the separation unit 23 separates each transmit antenna, a plurality of pilot blocks of the despread signal. Subsequently, after the delay profile is generated for each signal sent from each of the multiple transmit antennas using _{{(PLI 1, PLQ 1),} (2, PLQ 2 _PLI)} separated signals, the delay profile synthetic part 27 to synthesize multi-path selection for the delay profile. Then, based on the multipath delay profile selection, the multi-path selection is performed. Therefore, it is possible in the DS-CDMA system employing a transmission diversity system, and performs path search precision.
