Its valentine week..pass this to engineer girlfriend..nd she will more happy by looking into this cute valentine heart made in matlab..

FIR数字滤波器设计，分别让满足所设计的滤波器的通带、过渡带、阻带频率特性的正弦波通过滤波器，验证滤波器性能；(FIR digital filter design, respectively, so that the design meets the filter passband, transition zone, stop-band frequency sine wave pass filter characteristic, verify filter performance )

用matlab做得仿真，对图像进行DCT变换，分成8*8的块(matlab based simulation,dct transtion,8*8 block)

基于HIO算法的破解POCS（基于约束集投影）加密系统的MATLAB程序。(HIO algorithm based on crack POCS (projection based on a set of constraints) MATLAB program encryption system.)

编写卡尔曼滤波程序实现航迹的滤波估计，并计算出误差，仿真曲线(Kalman filter procedure to prepare implementation of the filtering track estimate and calculate the error, the simulation curve)

ARAPPara_matlab 网格参数化的源码(ARAPPara_matlab code for parameterization of 3d mesh)

说明：  Computes fourier series

这是一个用来对超声图像进行滤波的算法，是我按照论文自己编的，效果与论文中的一样。是stick filter。(This is the one used on the ultrasound image filtering algorithm is in accordance with papers their own series, the effect paper. Stick the filter.)

this is an implementation of ldpc encoder and decoder in matlab. generator matrix, parity check matrix and the chennel are implemented seperately. the bit error rate performance is estimated for the ldpc code

此程序用于求非平稳信号的关联维数，最适用于原始信号的维数较低的情况(This procedure used for non-stationary signal correlation dimension, the most suitable for the original signal in the case of low dimension)
