OFDM系统仿真，调制方式BPSK，前向纠错，运行无误(OFDM system simulation，BPSK，FEC)

SC_FDMA(Single-carrier Frequency-Division Multiple Access)仿真(SC_FDMA(Single-carrier Frequency-Division Multiple Access) simulation)

通过计算机上的多媒体卡，按照下列过程进行声音信号的录制、处理和回放，观察处理前后的波形，同时比较声音信号处理前后的效果。 1、 将录制的信号反褶以后播放（反褶以后的信号移到t=0点开始）。 2、 将录制的信号改变取样率（相当于进行了尺度变化）以后播放。 3、 将录制以后的信号延时1s，并将幅度降低一半，接着与原来的信号相加，然后播放。(Multimedia card on your computer, follow the process for recording, processing, and playback sound signal waveform observed before and after treatment, while comparative effectiveness sound signal before and after treatment. 1, the signal recorded after deconvolution player (deconvolution signal moves after t = start 0:00). 2, the signal is changing the sample rate recording (is equivalent to a scale change) later playback. 3, after the recorded signal delay 1s, and reduce the rate by half, and then with the original signal are added, then play it.)

因子图和和积算法的matlab实现，给需要的人用，谢谢你的宝贵建议(factor graph and sum-product algorithm )

预测函数控制，可以跟踪自己设定的值，控制效果很好。(Predictive functional control, you can track their own set of values, the control works well.)
