| 摘要 |
One of the objects of the present invention is to more completely avoid impossibility of access between a mobile station and a base station, in wireless communication using an OFDM (Orthogonal Frequency Division Multiplexing) modulation scheme. In one embodiment, a base station removes a guard interval from an OFDM symbol received from a PHS terminal through a timing correction channel at two different timings to obtain two effective symbols, calculates a timing correction amount by including one timing, at which an guard interval is removed for the effective symbol that has caused detection of one correlation peak within a predetermined timing detection range of two correlation peaks detected from the respective effective symbols, into a differential from reference timing of the base station at the time of detection of the one correlation peak, and transmits the timing correction amount to the PHS terminal by means of a timing correction burst.
