本文利用Matlab／Simulink软件，以无线电调幅广播发射与超外差接收系统为例，对“通信电子电路”课程中重要的通信系统单元电路进行了仿真和分析，给出了仿真模型和较为详细的各点仿真波形，并结合实际给出了多路系统的仿真结果。将该Matlab仿真引入课程教学。可以使学生在学好课程的同时，了解和掌握通信系统建模与仿真的方法。(In this paper, the use of Matlab/Simulink software to the radio superheterodyne AM radio receiver system with the launch as an example, the " communication electronic circuits" course an important element of communication system circuit simulation and analysis, the simulation model and the more detailed Simulation waveform points, combined with the actual multi-channel system is given the simulation results. Matlab simulation of the introduction of the teaching. Will enable students to study courses at the same time, understanding and knowledge of modeling and simulation of communication systems approach.)

channel-coding_matlab
提高数据传输效率，降低误码率是信道编码的任务。信道编码的本质是增加通信的可靠性。但信道编码会使有用的信息数据传输减少，信道编码的过程是在源数据码流中加插一些码元，从而达到在接收端进行判错和纠错的目的(Improve the efficiency of data transmission, reduce the bit error rate is the channel coding task. The essence of channel coding is to increase the reliability of communication. But the channel coding can make data transmission of useful information is reduced, the channel coding process is to add some symbols in the source data stream, so as to achieve the purpose of erroneous judgment and correction at the receiver)

薛定宇教授编写的MATLAB控制分析工具包Ctrllab
如题，该工具包解压后，通过MATLAB修改路径后，直接运行ctrllab，即出现可视化界面，可进行时域、频域、复域的各种分析，比如bode图，奈氏图等等，超级好！对控制专业的同志来说，用处极大！(Prepared by Professor Xue Dingyu MATLAB control analysis tools package Ctrllab such as title, package and extract the tool MATLAB modify the path directly run ctrllab, that appear visualization interface, can be time-domain, frequency domain, the complex domain of all kinds of analysis, such as bode Figure Nyquist plot, and so on, super good! Comrades who control professional, extremely useful!)

基于GMM的说话人识别
语音识别是近年来发展非常迅速的一项计算机智能技术，广泛应用在语音控制、身份识别等多个领域。本次项目主要研究语音识别的预处理过程和特征参数的提取环节。通过对原始语音信号进行预加重和分帧、加窗，滤除低频干扰，提升对语音识别有用的部分，消除了部分噪音和失真。预处理之后进行信号的特征提取，主要选取了短时平均过零率和MFCC两个特征参数，应用matlab软件绘制波形图并提取特征参数矩阵，为之后的语音信号的识别打下了基础。(Speech recognition is a computer intelligent technology which has developed rapidly in recent years. It is widely used in speech control, identity recognition and other fields. This project mainly studies the pretreatment of speech recognition and the extraction of feature parameters. Through pre-emphasis, framing and windowing of the original speech signal, the low frequency interference is filtered out, the useful part of speech recognition is enhanced, and some noise and distortion are eliminated. After pretreatment, feature extraction of signal is carried out. Two feature parameters, short-term average zero-crossing rate and MFCC, are selected. Waveform diagram is drawn by MATLAB software and feature parameter matrix is extracted, which lays a foundation for speech signal recognition.)
