matlab code about image processing

使用m语言对OQPSK调制方式进行仿真模拟，可以得到OQPSK调制前后以及加噪前后基带信号对比、频谱对比、星座图和误码率(您是不是要找： 使用c语言对QPSK调制方式进行仿真模拟,可以得到OQPSK调制前后以及加噪前后基带信号对比、频谱对比、星座图和误码率 Use m language OQPSK modulation system simulation, you can get around the OQPSK modulation, and baseband signal plus noise before and after contrast, spectral contrast, constellation diagrams and bit error rate)

基础的音频处理matlab程序，设计巴特沃斯低通数字滤波器实现滤波。(Matlab-based audio processing procedures, Butterworth low-pass digital filter designed to achieve the filtering.)

some matlab codes for image processing

说明：  是cso得源代码，里面有详细的写法，主要有速度和位置更新公式(It is the source code of cso, which has detailed writing, mainly including speed and position update formula)

本程序是用matlab程序语言编写的costas环仿真程序，并对于模拟的costas环的性能进行了分析，costas环主要用于载波同步，本设计实现了对于载波频率跟踪的实现，并且给出图形对比(The program is written in matlab program costas loop simulation program, and the simulated performance of costas loop analysis, costas loop is mainly used for carrier synchronization, the design achieved the realization of the carrier frequency tracking, and gives graphic correlation)

这是VAD有关代码。也就是说为了在音声中找到activity voice 用GAET方法来决定阈值，然后判别了无音区间。(voice activity detection)

自己做的感应电机无速度传感器直接转矩控制仿真模型，特拿来分享，还望大家多多指教。(sensorless direct torque control for induction motor)
