source code of PSO(Particle Swarm optimization)

这是一个三相离网逆变器双闭环控制，基于dq坐标系下采用电压外环和电流内环的方法对其进行稳定性控制。(This is a three-phase off-grid inverter double closed-loop control, based on the dq coordinate system using the voltage outside the ring and the current inner ring method for its stability control.)

kaiser窗的FIR低通滤波器，可以直接调用，滤波器阶数为75阶，通带为500HZ，阻带为600HZ，根据实际需要可直接改动通带、阻带频率。

对于搞图像分析和机器视觉的同志是一本很不错的书籍(usefull to these peple who major inmachine vision and imaging process)

利用傅里叶变换的方法，求含有噪声的两个序列的互相关函数(a method of getting cross correlation function)

MATLBA 信道仿真,完成信道卷积码循环码的编译码(MATLBA channel simulation complete Channel Convolutional Codes cycle code encryption)

用matlab实现了CDMA系统的RAke接收机，比较最大比合并，等增益合并和选择式合并接收机的性能(Using matlab to achieve a CDMA system RAke receiver, compare maximal ratio combining, equal gain combining and selective merge receiver performance)

使用capon进行测向，对加过幅相误差的信号进行测向，得出其俯仰角和方位角的误差(Use capon were finding of increased over amplitude and phase error signal to be measured, draw its pitch angle and azimuth error)

混沌粒子群算法用于图像分割，程序已调试好，并用多种图像提供使用。分割效果显著。(Chaotic particle swarm optimization algorithm for image segmentation, the program has been debugged, and use a variety of images available. Segmentation effect is remarkable.)
