Abstract:
A method for receiving a signal in a wireless communication system based on Multiple-Input Multiple Output (MIMO)—Orthogonal Frequency Division Multiplexing (OFDM) through multiple antennas. In the system, weight for a zero forcing based equalization matrix is determined by inverting a channel transfer matrix for each subcarrier of the signals. The original data transmitted is recovered by combining data subcarriers from different receive antennas using the calculated weights thus reducing the system complexity.
