说明：  awgn 信道下 ldpc与FQPSK的串行级联系统，(AWGN channel，serially concatenated FQPSK modulation system with ldpc)

a toolbox that makes an interface to export files from catman to matlab

信号与系统matlab作业，实现卷积操作，供学习信号与系统的同学们参考(1. Define two signals as: x1[n] =   n, 0 < n  N1+1 2 N1 − n+ 1, N1+1 2 < n  N1 0, elsewhere and x2[n] =  1, 0 < n  N2 0, elsewhere We let N1 = 999 and N2 = 500. (a) (30 )Write a MATLAB function myconv to compute x1[n]x2[n] where  denotes the convolution sum. You have to plot your result and attach it in your report. You may use the MATLAB function conv to check whether your result is correct.)

本段程序是在基于matlab开发环境下来进行语音信号滤波器的设计。实用性非常好。(The voice signal segment program is based filter design matlab development environment down. Practicality is very good.)

文件包含加拿大IPIX雷达netcdf格式的雷达数据，netcdf数据提取到matlab的工具箱，以及在处理IPIX雷达数据时需要注意的问题说明。(It contain Radar seaClutter data in netcdf format IPIX radar located in Canada. also, a toolbox for extracting mat data the netcdf data is in it. by the way , a specific instruction is contained in the file bag.)

两个复正弦加白噪声随机过程之和。用MUSIC方法进行信号频率谱估计。(The sum of two complex sinusoidal added white noise random process.The MUSIC method is used to estimate signal frequency spectrum.)

PMSM的矢量控制，坐标变化，三闭环，控制效果良好，波形不错(PMSM vector control, coordinate changes, three closed loop)

说明：  输出电压稳定不随输入电压、输出侧负载变化而变化，电流电压环pi参数已整定完毕，内外环配合良好。(The output voltage stability does not change with the input voltage and the load at the output side. The PI parameters of the current voltage loop have been set.)

ppt文件，是matlab的一些基础知识，很有用(ppt files, are some of the basics of matlab, useful)

一个计算用的matlab小程序，希望大家喜欢，谢谢(A calculation of the matlab small program I hope you like it, thank you)
