摘要：

Multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) transmission can improve both the transmission capacity and performance due to diversity gain. However, when the antennas are close to each other in a MIMO-OFDM system, the diversity order will be decreased because of channel correlation. In the paper performance of various detection methods for space-time block code (STBC) MIMO-OFDM with channel correlation are evaluated, including the conventional Alamouti full matrix detection, the modified diagonal matrix detection, the least square-zero forcing (LS-ZF) detection, and the successive interference cancellation (SIC). The paper also verify that the SIC detection can still keep excellent detection performance under large channel correlation.
