本代码是关于多天线技术空时块编码的通信系统仿真源程序，其中包括QPSK调制，QPSK解调，FFT,IFFT，STBC等模块,并给出误码率计算和性能仿真图。(The code is on the multi-antenna space-time block coding techniques of communication system simulation source code, including QPSK modulation, QPSK demodulation, FFT, IFFT, STBC and other modules, and gives the bit error rate and performance simulation map.)

说明：  Alamouti空时编码，16QAM调制(Alamouti Sapace Time Coding, 16QAM.)

This is the Kron Reduction algorithm. It is used to reduce Jacobian matrices to calculate state matrices.

Newtons method for power flow studies

说明：  雨流计数法，可以参考，用于雨流计数统计循环次数(Rain flow counting method)
