Abstract:
1. A method for detecting a Multiple Input Multiple Output (MIMO) signal in a wireless communication system, comprising: selecting from a first antenna a plurality of 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 plurality of first candidate signal constellations; updating the at least one second survivor path to remove an effect on the at least one second survivor path due to the plurality of first candidate signal constellations; selecting from a second antenna a plurality of 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 plurality of second candidate signal constellations; and acquiring a transmitting symbol among the at least one final survivor path, wherein a distance of the first survivor path is added with the first path metric so as to be updated, and a distance of the updated second survivor path is added with the second path metric so as to be updated.
