摘要 空时分组码是多输入多输出(MIMO)系统中采用的主要编码方法。在输入信号信噪比已知的基础上,结合信号星座图,分析了在Nakagami衰落信道中采用不同数量的发射和接受天线时系统的误码率。同时,在Nakagami信道中,当衰落系数m取不同值时,对系统的性能也作了进一步地分析,最后给出了Nakagam环境下信道容量的图形和表达式。 Space-time codes is the main encoding method which is adopted in MIMO system. Based on the known input SNR, this article analyses the bit error rate（BER） on Nakagami Fading Channel which adopts the multi-input and multi-output antennas system combines with the signal constellation graph. Meanwhile, we do more analysis on the system capability when the fading coefficient has different value on Nakagami Fading Channel. At last, it gives the expression and graph of channel capacity and on Nakagami Fading Channel.
