Abstract
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.
