本程序给出了通信体制中十分重要的chirp信号（即线性调频信号）的产生方法，希望能对大家有一定的用处(This procedure gives a very important communication system chirp signal (ie, linear FM signal) is produced, and I hope we can have some useful)

这是一个瑞丽信道的仿真程序，我试过，能运行，大家多多参考。(This is a Ruili channel simulation program, I tried to run, everyone can reference.)

说明：  matlab科学计算的几乎所有数学算法以及仿真。每一个m文件在我学习的时候都验证了其正确性。前面的比较简单，逐步深入。另外对部分算法本人在学习中做了优化，更简洁。(matlab scientific computing almost all mathematical algorithms and simulation. M each file in my learning at all times to verify its correctness. In front of a relatively simple step by step in depth. In addition to some algorithm I have done a study of optimization, a more concise.)

In this section, the PAPR performance of the proposed algorithms is shown. To evaluate the PAPR performance, the CCDF is employed. The specification detail of simulation parameters is given in TABLE I. In Fig. 5 is shown the PAPR with a PTS method (U = 8) and conventional PTS (U = 4) are improved 4.3 dB and 2.6 dB from ordinary MIMO-OFDM signal when CCDF = 10− 4 respectively and Fig. 6 is shown the PAPR with an optimal PTS method in case of 128 subcarriers.

一个用matlab编写的绘制smith圆图的程序，简单明了，内有代码解释(One using matlab draw smith chart of the procedure is simple, there are code explanations)

It is MATLAB simulink file for simulating induction generators. It can be useful for fault analysis.

这是一个高斯混合模型的源代码,环境是matlab, 高斯混合模型运用于多个方面,在信号处理中应用非常广泛,初学者可以作为参考(This is a Gaussian mixture model of the source code, the environment is matlab, Gaussian mixture model applied to various aspects of signal processing applications in a very wide range of beginners can be used as reference)

自适应线性预测编码问题，利用白噪声序列生成信号序列，进而进行LMS迭代，计算滤波器权系数的轨迹曲线和衰减曲线(Adaptive linear predictive coding problem, the use of white noise sequence to generate signal sequence, and then LMS iteration to calculate the filter weights of the trajectory curve and the attenuation curve)
