摘要：A pilot signal detection method, a pilot signal detection apparatus and asubscriber in which the timing of a pilot signal of a neighbor base station is detectedcorrectly 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 rangeof correlation. The pilot signal for which the result of the partial correlation hasexceeded a first threshold becomes a pilot candidate signal for detection. Partialcorrelation is then taken of the pilot signal of the pilot candidate signal within a range ofcorrelation broader than the first range of correlation. The pilot signal for which theresult of the partial correlation has exceeded a second threshold becomes a pilotdetection signal.
