| Abstract: | Based on studying the performance of orthogonal space-time block codes over Rayleigh fading channels, a general expression of instant output signal-to-noise for orthogonal space-time block code over fading channel at the receiver is analyzed and the minimum distance sphere bound of the symbol error rate is derived for PSK modulation over Nakagami fading environment. Simulations demonstrate that the good performance of space-time block code by using multiple transmit antennas and receive antennas, the ＂floor effect＂ of the transmit-antenna number. |
