高速跳频，调制样式为DPSK(DPSK/FH)，包括信号的发射接收模型，自己写的代码，仅供参考。(High-speed frequency hopping, modulation pattern for DPSK (DPSK/FH), including the launch of signal reception model, write your own code, for reference purposes only.)

产生MDPSK信号的matlab源代码，分为4dpsk和8dpsk两种(MDPSK signals generated matlab source code is divided into two 4dpsk and 8dpsk)

我们做很多实验时得到的一些数字信号必须经过处理才能最终得到应用。此文件是matlab数字信号处理说明书，希望对读者有帮助(We do a lot of experiments to get some of the digital signal must be processed in order to ultimately be applied. This file is matlab digital signal processing instructions, hoping to help the reader)

4FSK的解调算法的设计，主要用于本科生通信工程初学通信原理课程或者大学生本科论文帮助，仅供参考！程序绝对正确！(4FSK demodulation algorithm design, mainly for undergraduate Communication Engineering the communication principle beginner course or college students undergraduate thesis help, for reference purposes only! The program is absolutely right!)
