ABSTRACT:
A wireless communication apparatus for performing reception processing while tracking a symbol timing obtained by synchronization, the wireless communication apparatus includes a resampler for performing resampling to oversample a received symbol in a plurality of phases by using a sampling rate higher than a symbol rate, a phase-error detector for obtaining a phase error in a time sequence at each of sampling points where the resampling is performed, an error-signal generator for generating an error signal on the basis of the phase error detected at each of the sampling points where the resampling is performed, and a sampling point controller for detecting an offset direction at each of the sampling points on the basis of the error signal and for controlling an offset direction of each of the sampling points of the received symbol.
