电话拨号音的合成与识别 基于对电话通信系统中拨号音合成与识别的仿真实现，主要涉及到电话拨号音合成的基本原理及识别的主要方法，利用 MATLAB 软件以及 FFT 算法实现对电话通信系统中拨号音的合成与识别。并进一步利用 MATLAB 中的图形用户界面 GUI 制作简单直观的模拟界面。使其对电话通信系统拨号音的合成与识别有个基本的了解。 能够利用矩阵不同的基频合成 0 － 9 不同按键的拨号音，并能够对不同的拨号音加以正确的识别，实现由拨号音解析出电话号码的过程。(Synthesis and recognition telephone dial tone Based on telephone communication system dial tone Simulation synthesis and recognition, mainly related to the basic principles of the main methods telephone dial tone synthesis and recognition, using MATLAB software and the FFT algorithm for synthesis and recognition telephone communication system dial tone. And further use of MATLAB graphical user interface is simple and intuitive GUI making analog interface. Synthesis and recognition make telephone communication system dial tone have a basic understanding. Can be different the fundamental frequency of matrix synthesis 0 9 dial tone different keys, and can be correctly identify different dial tone, dial tone achieved by the parsed telephone number of processes.)

随机生产模拟以等效电量法为研究方法，以王锡凡编撰的电力系统优化规划例3-1为算例实现(Stochastic production simulation with equivalent power law research methods to compile PROCEEDINGS power system optimization planning cases as examples to achieve 3-1)

说明：  对二维图像去噪，使用分数阶傅里叶变换算法。(For two-dimensional image denoising, fractional Fourier transform algorithm is used.)

A bad MATLAB data for the algorithm as a DTW model. It can′t recognise the number of 0-9. Do not try it, just do not run testdtw.

在高斯信道下，采用16QAM,维特比编码的64子载波的OFDM系统(the Gauss channel, using 16QAM, Viterbi encoding of the 64 subcarrier OFDM system)

An exception indicating that a cursor is out of bounds.

说明：  watterson信道matlab仿真,瑞利衰落。。。。(This example shows how to simulate High-Frequency (HF) ionospheric channels, based on the models described in Recommendation ITU-R F.1487. In particular, it shows how to simulate the general Watterson channel model, and other simplified channel models used in the quantitative testing of HF modems. It makes use of the Rayleigh multipath fading channel object and the Gaussian and bi-Gaussian Doppler structures from Communications System Toolbox.)

说明：  LMS算法对语音进行去噪，matlab平台。(LMS algorithm for speech denoising, Matlab platform.)
