这是一个定点的多带OFDM物理层发射机/接收机模型,共122个子载波，22个导频，采用QPSK调制,5/8前向纠错码(删余卷积码.)-This is a sentinel of the multi-band OFDM physical layer transmitter/receiver model, a total of 122 sub-carrier. 22 pilots, using QPSK modulation, 5/8 prior to the error-correcting code (I delete convolutional codes.)

接口程序连接 Actidyn 模拟器 （最准确的 3 轴旋转表） 到仿真软件等系统工具套件 （STK） 通过 Matlab 环境。

A simple example to verify the feasibility of applying compressed sensing for channel estimation. The pilot applies a PN pattern in the frequency domain. The density of pilot is less than the Nyquist sampling rate. Also it is assumed there are sparsity in the channel taps, which is the basis for applying compressed sensing.

利用卷积编码和BPSK调制方式，关于高斯白噪声信道下信噪比与比特误码率关系的Simulink仿真-The use of convolutional coding and BPSK modulation on the Gaussian white noise channel ,the relationship between SNR and bit error rate using Simulink simulation

串口调试：这还是个初步的！如果你有兴趣还可以自己再改！如果还有更好的请联系我-serial debugger : This is still preliminary. If you are interested in then they can change! If there is a better contact I
