Abstract:
1. Wireless communication device for use in a wireless communication system having a plurality of base stations for transmitting known signals using different subcarriers, comprising: a Fourier transform processing unit performing Fourier transform processing respectively on a plurality of received signal portions whose reception periods have a predetermined time difference; a selector selecting a signal corresponding to a subcarrier including the known signal, from among the signals corresponding to the plurality of subcarriers obtained by the Fourier transform processing unit; and a correlation detector performing correlation calculation to obtain correlation of the signals respectively corresponding to the plurality of subcarriers selected by the selector with the known signal, and selecting the synchronous timing of another base station different from the base station presently in communication, from among the start timing sets of the plurality of received signal portions based on the correlation obtained by the correlation calculation.
