OFDM

说明：  用于生成正交频分复用OFDM信号的Matlab仿真程序代码全面(Matlab simulation code for OFDM signals)

傅里叶变换能将满足一定条件的某个函数表示成三角函数(正弦和/或余弦函数)或者它们的积分的线性组合(Fourier transform to meet certain conditions can be expressed as a function of trigonometric functions (sine and/or cosine functions) or their linear combination of the integral)

实现快速傅里叶变换函数的matlab程序，以2D作为基来写的(Fast Fourier transform function matlab program to 2D as a base to write)

实现了huffman编码 运行良好 可以在不同的版本中运行(Achieve a huffman encoding)

关于小波去噪的算法，总结性比较好，非常全，对初学者非常适用。( Wavelet denoising algorithm, summary is better, very full, very suitable for beginners.)

本光盘包含《MATLAB工程计算及分析》一书全部的源程序文件。对大量的工程实例进行了详细的分析计算。(matlab caculate and analysis for projects， include the mode set up and so on.)

三相全桥可控整流电路的simulink仿真,改变触发角并通过示波器来观察线电流、负载输出电压和电流(three-phase full-bridge controlled rectifier simulink)

I wrote this program for coloring any map with only 4 colors. Input for it is an bitmap file with 24 bit colors (must gray/scale). Output is a bitmap which is colored with maximum 4 colors.

说明：  一个函数int fun(int *s,int t,int *k),用来求除数组的最大元素在数组中的下标并存放在k所指的储存单元中(A function int fun (int* s, int t, int* k), for requirements in addition to an array of the largest element in the array subscript coexist on the storage unit referred k)

双馈电机 控制 波形很好 参数调节的很正确 得出了好的控制效果(Double-fed motor control waveform parameter adjustment is very well drawn correctly good control effect)
