    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： A method and apparatus for detecting a signal in a communication system using at least two transmit antennas are provided. The signal detection method and apparatus includes selecting a symbol corresponding to a lowest branch metric from among symbols, the number of which corresponds to a modulation scheme, determining a candidate symbol by extending a process of selecting a symbol corresponding to a lowest branch metric from among the selected symbols, to a number which is less by one than the number of the transmit antennas, setting an accumulated branch metric of the candidate symbol as a threshold, removing a symbol having an accumulated branch metric higher than the threshold, and selecting, as a last received symbol, a symbol corresponding to a path having the lowest accumulated branch metric among paths selected without being removed until a last stage.
