Abstract
A method for detecting a multiple input multiple output (MIMO) signal in a wireless communication system is provided. The method includes: selecting from a first antenna each of the first candidate signal constellations in which a first path metric for at least one first survivor path is minimal; acquiring at least one second survivor path based on the first candidate signal constellations; updating a second survivor path so as to remove an effect on the second survivor path due to the first candidate signal constellations; selecting from a second antenna each of the second candidate signal constellations in which a second path metric for the at least one updated second survivor path is minimal; acquiring at least one final survivor path based on the second candidate signal constellations; and acquiring a transmitting symbol among the final survivor paths.
