<p>The complex product of each of the complex conjugate patterns of the pilot patterns assigned to the respective transmission antennas of a base station and each of the despreading signals (ISI, ISQ) of the reception signal generated by a despreading section (22) is calculated. A separating section (23) separates the pilot blocks of the despreading signals for each antenna. By using the separated signals {(PLI1, PLQ1), (PLI2, PLQ2)}, a delay profile for each signal transmitted from the transmission antennas is created, and a multi-path selection delay profile is synthesized by a delay profile synthesizing section (27). According to the multi-path selection delay profile, multi-path selection is conducted. As a result, highly accuracy path search can be conducted in a DS-CDMA system adopting the transmission diversity scheme.</p> |
