	<span style=\"line-height:1.5;\">在n-Rayleigh信道下，研究了使用发射天线选择(TAS)和正交空时分组码(STBC)的多输入多输出(MIMO)系统的平均符号误码率(ASEP)性能。基于标量加性高斯白噪声(AWGN)信道的方法，得到了系统使用多进制正交幅度调制(MQAM)和多进制相移键控调制(MPSK)，在接收端的信噪比的表达式。然后对不同条件下的ASEP性能做了数值仿真，仿真结果表明：随着发射天线或接收天线数的增加，系统的ASEP性能得到了很好的改善，当使用QPSK调制，SNR = 12 dB，(3,3; 6)系统的误码率是2 × 10<sup>？3</sup>, (4,4; 8)系统的误码率是2 × 10<sup>？4</sup>, (5,5; 10)系统的误码率是2 × 10<sup>？5</sup>。&lt;br/&gt;The average symbol error probability (ASEP) of multiple-input multiple-output (MIMO) systems employing transmit antenna selection (TAS) and orthogonal space-time block code (STBC) under n-Rayleigh fading channels is investigated in this paper. Based on the scalar additive white Gaus-sian noise (AWGN) channel approach, the exact form expressions of the signal-to-noise ratio (SNR) at the receiving end are derived for multiple quadrature amplitude modulation (MQAM), and mul-tiple phase shift keying modulation (MPSK). Then the ASEP performance under different conditions is evaluated through numerical simulations. Simulation results show that: the ASEP performance can be improved with the increase of the number of transmit antennas or receive antennas, when SNR = 12 dB, the ASEP of (3,3; 6) with QPSK is 2 × 10<sup>？3</sup>, (4,4;8) is 2× 10<sup>？4</sup>, (5,5; 10) is 2 × 10<sup>？5</sup>.</span>
