This scheme is also called DPSK since MZ modulator provides the “digital” phase modulation if it is biased at null instead of quadrature. No coherent detection is needed if data is differentially pre-coded.

MATLAB_GUI设计-专题讲稿-王正盛。matlab gui使用指导，教您gui的基本使用及入门。(matlab gui)

卷积码编码器，对二进制向量进行编码，希望对大家有帮助(Convolutional code encoder, to encode binary vector, in the hope that everyone has to help)

贪吃蛇，大家都知道了，这个界面有点粗糙。顺便请问一下axis的 drawmode 设为 normal 　或　 fast 有什么区别。(As we all known, this is the snake game. The GUI isn t very well. By all means, it is not bad to make it by MATLAB.)

Pitch-scale and time-scale modification of speech by PSOLA techniques.

说明：  利用IIR滤波器设计一个低通滤波器，能够分析到电力系统中的三次谐波，要求满足如下指标：截止频率150HZ，阻带衰减≥30db(IIR filter design using a low-pass filter, to analyze the power system in the third harmonic, the requirements to meet the following indicators: cut-off frequency 150HZ, stopband attenuation ≥ 30db)

这个程序是一个风力机的三阶模型，采用桨距角控制，设计了转速的闭环控制系统(This program is the third-order model of a wind machine, using the pitch angle control, closed-loop control system design speed)
