完成M=4正交信号的数字通信系统的蒙特卡罗仿真(The completion of M = 4 orthogonal signals in Monte-Carlo simulation of digital communication systems)

16QAM通过带限信道，设码元速率为1000波特，传输的滚降系数是0.75的滚降升余弦滤波器(16QAM by band-limited channel, set the symbol rate is 1000 baud, roll-off factor of transmission is 0.75 rolloff raised cosine filter)

this is the code to calculate magical hilbert transform of a signal.

说明：  good ocr program for matlab

说明：  计算生物二叉树的matlab具体程序，有需要的来看看啦(Calculation of the biological tree of matlab specific procedures, there is a need to look at the看啦)

读入文件，对文件进行无损预测编码和解码，然后对文件进行DM编码和解码(Read the file, the file lossless predictive coding and decoding, and then the file encoding and decoding DM)

远程操作串行端口源码，非常值得收藏~~~~~~~~~(Remote COntrol Serial Port，very precious)

Writes seismic data from Matlab workspace to a segy format file on disk.

是用Matlab求得自相关函数的源代码，对刚接触自相关互相关方面的同学有很大帮助！(Is the autocorrelation function obtained using Matlab source code for the new to the inter-related aspects of the autocorrelation of great help to the students!)
