清华大学胡广书教授的《现代数字信号处理教程》的源程序。学信号处理或通信专业的都知道，胡广书教授在业界是赫赫有名的，读他的书，再读这些程序，你能深刻理解现代信号处理的精华，并会应用。(Tsinghua University Professor Hu Guangshu the modern digital signal processing tutorial, the source. Learning signal processing or communications professionals are aware, Professor Hu Guangshu is known in the industry, reading his books, read these procedures, you can deeply understand the essence of modern signal processing and application.)

自己编的5种调制信号，LZ复杂度反映的是一个时间序列中，MIMO OFDM matlab仿真。( Own five modulation signal, LZ complexity is reflected in a time sequence, MIMO OFDM matlab simulation.)

说明：  使用AOA算法进行定位仿真，经过测试真实可用(AOA algorithm is used for positioning simulation, which is real and available)

LDPC码编译码源程序，可生成任意非规则二进制校验矩阵，并可进行LLR BP译码(LDPC codec source code can be generated non-arbitrary rules binary check matrix, LLR BP decoding can be carried out)

这是通信系统仿真的第五章的例题的仿真程序代码！挺好的，希望对大家有用！(Communication System Simulation This is the fifth chapter of the simulation program code examples! Very good, and I hope useful for everyone!)

说明：  matlab代数方程的解法，相信对做数值计算和模拟的有很好的帮助(matalb solve code for equation )

成功的模拟DBPSK误码率，而且精度特别高，值得学习的人好好借鉴一下(BER simulation of DBPSK successful, but accuracy is particularly high, it is a good reference to learn about people)

bit error rate versus capacity

说明：  用于检测微弱信号的Duffing系统，这是我的毕业设计一部分，因为我做的时候也曾求取过很多资料，但是并没有找到，因此在我完成之后，上传这个代码，希望这个能帮助别人。 里面还有后续做的GUI界面实现的Duffing振子检测功能，可检测信号幅值和频率。(The Duffing system for detecting weak signals, this is part of my graduation project, because I also asked for a lot of information when I did it, but it was not found, so after I finished, upload this code, I hope this can help others.)

拉格朗日插值法matlab源程序，具有通用性和可扩展性。(Lagrange interpolation matlab source, has the versatility and scalability.)
