一个复信号Zt=Sr+jSi可以看作是一个实信号Sr与一个虚信号Si的合成·由于任何一个只含有时间t为自变量的信号都可以视为一条二维曲线，则两个分别以时间为唯一自变量的信号Sr与Si的叠加可以看成是一条随着时间延伸的三维曲线·
The coding matrix linked with different transmits is simulated by the real-value signal and complex-value signal, and the effect of different modulations on the error coding is worked over.
