EQUALIZER FOR A SINGLE-CARRIER RECEIVER AND EQUALIZATION METHOD THEREFOR

摘要

An equalizer for a single-carrier receiver having an enhanced convergence speed and a steady equalization performance. A filter unit filters received multi- path signals. A field synch extractor extracts a field synch signal having two signals of different levels from the received signals and a field synch storage unit stores a kth field synch signal of the extracted field synch signal. An error calculator N times repeatedly uses th e kth field synch signal and calculates equalization error values, wherein the filter unit use s the equalization error values to update coefficients of the filters. Accordingly, the equaliz er N times repeats the kth field synch signal to be compared to a reference signal generated fr om the field synch generator, so as to be operated in a training mode, to thereby enhance the convergence speed of the equalizer.
