Channel estimation LS MMSE

16QAM调制与解调的全过程，能够观察眼图、星座图、误码率等，方便研究运用16QAM调制解调的系统的性能(16QAM modulation and demodulation of the entire process, be able to observe the eye diagram, constellation diagram, error rates, facilitate the study of the use of 16QAM modulation and demodulation of the system s performance)

说明：  快衰落多输入多输出信道中，无信道状态信息的酉空时调制。属于信道发射和接收两端均无信道状态信息的非相干空时码。程序包含一个主程序和一个酉空时信号产生子程序，并给出误比特率。(Unitary space-time modulation without channel state information in fast fading MIMO channels. It belongs to the incoherent space-time code with no channel state information at both ends of the channel transmitting and receiving. The programs include a main program and a unitary space-time signal generation subroutine, and gives the bit error rate.)

this is simply a report on the fading channel on different modulation scheme
