在matlab环境下实现了对MPSK通信系统的仿真，(mpsk)

详细介绍了matlab中的ODE函数求解偏微分方程组的各种方法，附带示例，适合初学者学习。(Details of the ODE function matlab various methods for solving partial differential equations, with examples, for beginners to learn.)

说明：  剪切波代码实现 有Matlab和python两个版本 都是可以运行和跑通的(The implementation of shear wave code has two versions: MATLAB and python, which can run and run.)

说明：  录制一段个人的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；给定滤波器的性能指标，采用双线性变换法和窗函数法设计滤波器，并画出滤波器的频率响应；然后用自己设计的滤波器对采集的信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，分析信号的变化；回放语音信号；最后，设计一个信号处理系统界面。(Record a personal voice signal, and recording the signal is sampled draw sampled speech signal time-domain waveform and frequency spectrum for a given filter performance, the bilinear transformation and design of filter window functions and draw the frequency response filter then filter of their own design collection of the signal filtering, to draw the filtered signal in time domain waveforms and frequency spectrum, and filtering the signal before and after comparison, analysis of signal changes playback audio signals Finally, a signal processing system interface design.)

求解量子力学的薛定谔方程，说明见readme.ttxt，使用matlab编制。能现运行start.m (Solving the Schrodinger equation of quantum mechanics shows see readme.ttxt, using matlab prepared. Can now run start.m)

OFDM系统 发射、接收源程序，还有一篇文章说明哦，是OFDM系统学习不错的例子(OFDM system transmitter and receiver of the source, there is an article note Oh, OFDM system is a good example of learning)

matlab中冒号的使用总结，希望对大家有用(Summary of the use of matlab colon, we want to)

旋转不变技术估计信号参数(ESPRIT)算法是子空间估计的两个经典方法,它们都能够有效地估计特征子空间。程序包里面实现了用LS估计和TLS估计的ESPRIT算法。(ESPRIT estimates signal parameters (ESPRIT) algorithm is estimated that sub-space of two classical methods, they will be able to estimate the characteristics of effective subspace. Inside a package with LS estimates and estimates of the ESPRIT algorithm TLS.)
