<P>PROBLEM TO BE SOLVED: To simplify a pass timing detection process to achieve superior detection characteristics. <P>SOLUTION: A signal is despread over a plurality of chip timings for every antenna. A despread signal series for every antenna is received with a multi- beam to output a signal series for every beam and generate a delayed profile for every beam averaged over a constant period. A plurality of pass timings are detected in a process of selecting high-level chip timings one after another from the delayed profiles of all beams, without selecting those chip timings of less than a minimum selection timing interval centering around already selected chip timings in the following pass timing detection, and without selecting those chip timings of less than a minimum selection timing interval centering around beams of already selected chip timings with beams of less than a minimum selecting beam interval in the following pass timing detection. <P>COPYRIGHT: (C)2004,JPO |
