在MIMO2*2的无线信道环境下，运用OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术，发送信号，经过奇异值分解预编码，调制，在接收端解调，均衡，最终等到估计信号，并计算了整个系统的误码率；(In the wireless channel environment MIMO2* 2, the use of OFDM (Orthogonal Frequency Division Multiplexing) that is an orthogonal frequency division multiplexing, transmission signal, through a singular value decomposition of the pre-encoding, modulation, demodulation at the receiver, equalization, until the final estimated signal, and calculate the error rate of the whole system )
