代码说明：

说明：摘要：用MATLAB对基带数据传输解调检测进行仿真，推导不同先验概率下，接收端最小错误的判决门限。仿真不同先验概率下的误码性能，二进制与多进制的误码性能比较，码间串扰对误码性能的影响，及频偏对串行通信误码率的影响。关键词：MATLAB，基带传输，检测，判决门限 (Abstract: Using MATLAB for baseband demodulation simulation data derived under different prior probability, the receiver decision threshold minimum error. Simulation under different prior probability of error performance, binary and multi-bit error performance of binary comparison ISI on the BER performance, and the offset of the serial communication error rate. Keywords: MATLAB, baseband transmission, detection, decision threshold)

【Matlab界面GUI添加背景图片】：好像桌面背景一样，添加自己想要的背景图片，这里面有个技术，可以让背景不影响GUI界面的文字，edit、text。具体代码下载了解一下吧，平时工作总结的方法。(Matlab interface [GUI] Add a background image: It seems as desktop background, you want to add your own background image, and there are a technology that allows the background without affecting the GUI interface text, edit, text. Specific code to download understand it, the usual method of summing up the work.)

Linear prediction follows naturally from the general mathematics of linear systems. As the system output is defined as a linear combination of past samples, the system’s future output can be predicted if the scaling coefficients bj and ak are known.
