Abstract
A method for signal detection using a log likelihood ratio in a multi-input multi-output communication system includes reconfiguring the signals received through the reception antennas on the basis of channel characteristics and acquiring candidate groups for each transmission symbol by acquiring a signal constellation of one quadrant with respect to signals generatable for each transmission symbol and signal constellations for the remaining quadrants on the basis of the reconfigured signals.
