Time-frequency correlation-based synchronization for coherent OFDM receiver

摘要

There is provided an apparatus for synchronizing pilots contained in symbols received by a receiver in a multicarrier transmission system and a method thereof. Time-frequency correlation-based scheme, with exploitation of time-frequency correlation characteristics of the pilots, is used for identifying the positions of the pilots in time and frequency dimensions consisting of received symbols. The apparatus includes a pilot compensator and a signal selector for determining at least one correlation set, a correlator for generating one correlation set result for each of the correlation set, and a judgment unit for determining positions of the pilots in response to the correlation set result.
