    摘要: An apparatus and method for compensating for a phase error in a wireless communication system are provided. The apparatus includes a reception modem, a transmission modem, a Common Phase Error (CPE) compensator, a first channel estimator, a phase compensator, and a second channel estimator. The reception modem demodulates and decodes a signal received. The transmission modem encodes and modulates a signal for transmission. The CPE compensator compensates for phase errors of at least two symbols constituting a signal. The first channel estimator estimates channels for respective bursts. The phase compensator compares phases for the channels for the respective bursts with each other and compensates for a phase difference between at least two bursts. The second channel estimator estimates an interference channel.

    摘要: An apparatus and method for adaptively adjusting a target Received Signal Strength Indicator (RSSI) for Automatic Gain Control (AGC) in a full-duplex relay apparatus with an interference cancellation function. A Signal to Interference Ratio (SIR) estimation block estimates an SIR based on an interference signal estimated from a received signal and an interference-cancelled signal determined by cancelling the estimated interference signal from the received signal. A target RSSI determination block determines a target RSSI according to the estimated SIR. An AGC block adjusts a gain for the received signal based on the determined target RSSI.

    摘要: An apparatus and method for receiving data in a communication system. A Mobile Station (MS) receives a Base Station (BS) signal and a Relay Station (RS) signal, measures strengths of the received BS signal and RS signal, determines whether the BS signal acts as interference to the RS signal depending on the measured strengths of the RS signal and the BS signal, and transmits the determination result to an RS in communication with the MS. The RS allocates resources using resource allocation information for the BS signal that acts as interference, and the MS receives data using the resource allocation scheme allocated from the RS.
