Abstract
Error rates of multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) signals on frequency selective Nakagami-m fading channels are considered in this paper. For frequency-selective fading Nakagami-m channels,the magnitudes of the channel frequency responses approximate to be Nakagami-m distribution random variables (RVs),but the fading and mean power parameters are different from the counterparts in the time domain. Based on this result, the performance of a MIMO-OFDM system with space-time block code (STBC) diversity at the transmit antennas and maximum ratio combining (MRC) diversity at the receive antennas over Nakagami-m fading channels is analytically evaluated.
