当空间调制系统传输5bits信息时，采用8QAM，16QAM调制方式的比较。-When the spatial modulation 5bits information transmission system, the use of 8QAM, 16QAM modulation of the comparison.

当空间调制（sm）系统中每个符号含有3bits信息(即3bit/s/Hz的频谱利用率)时我们选择：4根发送天线，BPSK调制方式和2根发送天线，4QAM调制方式进行比较。-When the spatial modulation (sm) system, each symbol comprising 3bits information (i.e. 3bit/s/Hz spectral efficiency) when we choose: four transmitting antennas, B
