ABSTRACT:
A pilot signal detection method, a pilot signal detection apparatus and a subscriber in which the timing of a pilot signal of a neighbor base station is detected correctly and efficiently for improving the quality of communication of a mobile station. Partial correlation is taken of a pilot signal of an arbitrary base station within a first range of correlation. The pilot signal for which the result of the partial correlation has exceeded a first threshold becomes a pilot candidate signal for detection. Partial correlation is then taken of the pilot signal of the pilot candidate signal within a range of correlation broader than the first range of correlation. The pilot signal for which the result of the partial correlation has exceeded a second threshold becomes a pilot detection signal.
