Abstract:
1. A method for signal detection in a multi-input multi-output communication system receiving signals transmitted through a plurality of transmission antennas by using a plurality of reception antennas, the method comprising: detecting symbol candidate vectors with respect to transmission symbols transmitted through the plurality of transmission antennas on the basis of the signals received through the plurality of reception antennas; calculating Euclidean distances with respect to all the detected symbol candidate vectors; and detecting a vector having a minimum Euclidean distance among the symbol candidate vectors as a final symbol vector for each of the transmission symbols, wherein the detecting of the symbol candidate vectors includes: wherein the error expected values are error expected values for errors generated when a corresponding symbol is mis-determined as a detection target, wherein the determining of the symbol to be detected at present includes: wherein the determining of the symbol based on the reception filter matrix and based on the reordering matrix includes:
