摘要： A method for detecting and decoding a signal in a communication system based on Multiple-Input Multiple-Output (MIMO)-Orthogonal Frequency Division Multiplexing (OFDM). A signal is received through multiple receive antennas. A decision error occurring at a symbol decision time is considered and a symbol is detected from transmitted symbols. Original data transmitted from the detected symbol is recovered. The performance of a coded bit system can be significantly improved using a new equalization matrix G considering a decision error.
