Timing phase information is extracted from a power spectrum of a received signal whose amplitude is modulated per frame or sub-frame, and timing phase synchronization of the received signal is performed with the timing phase information. Also, a vector signal of the power spectrum is generated, the vector...http://www.google.com.au/patents/US7394848?utm_source=gb-gplus-sharePatent US7394848 - Method and apparatus for time equalization
