Abstract:
1. An apparatus for compensating for a phase error in a Relay Station (RS) of a wireless communication system using a Full Duplex Relay (FDR) scheme, the apparatus comprising: a reception modem configured to demodulate and decode a signal received through an antenna; a transmission modem configured to encode and demodulate a signal for transmission to a receive end; a Common Phase Error (CPE) compensator configured to compensate for phase errors of at least two symbols constituting a signal provided from the reception modem; a first channel estimator configured to estimate channels for respective bursts using a signal provided from the transmission modem and a signal provided from the CPE compensator; a phase compensator configured to compare phases for the channels for the respective bursts provided from the first channel estimator with each other and configured to compensate for a phase difference between at least two bursts; and a second channel estimator configured to estimate an interference channel considering channels for the at least two bursts compensated for the phase difference.
