Patent ID: 7912168

Claim:
A wireless communication apparatus for performing reception processing while tracking a symbol timing obtained by synchronization, the wireless communication apparatus comprising: 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 sampling point 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; 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; and a rotation-direction detector for detecting a rotation direction of a symbol at each of the sampling points where the resampling is performed, wherein the error signal output from the error-signal generator is sampled at the time a rotation of the symbol reaches a predetermined angle in the rotation-direction detector.
