Abstract: A detecting method of a multiple-input multiple-output system includes the steps of: a) canceling interference between transmit signals by assigning weight values to signals received through a plurality of antennas, and determining K optimal antenna signals through channel gain estimation; b) calculating L transmit signal estimation values by quantizing the optimal antenna signals according to a predefined constellation size of L; c) calculating L residual antenna signals, in which interference of the transmit signal estimation values is removed from the received signals using the L Tx signal estimation values; d) calculating L residual transmit signal estimation values by quantizing the L residual antenna signals according to the predefined constellation size; and e) creating K×L estimated transmit signal candidate groups by repeating the calculation of the L residual transmit signal estimation values for each of the K optimal antenna signals, and detecting transmit signals from the estimated transmit signal candidate groups.
