SIFT

说明：   Direct Sequence Spread Spectrum

求解一维热方程。空间方向采用四阶差分格式，时间方向采用bvm法(Solving one-dimensional heat equation. Spatial orientation difference scheme with fourth order, the time direction by bvm method)

This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious. (This is a JPEG encoding & decoding program of still image. It does not use level shifting.

仿真基本LMS算法(basic LMS algorithm simulation)

说明：  高质量的OFDM仿真代码，有误码率仿真图。非常好用。(OFDM simulation of high-quality code, bit error rate simulation map. Very easy to use.)

this is the code for detection of heart rate

说明：  这是基本Matlab的仿真原码，功能是验证无码间干扰的条件，包含了滚降滤波，参杂噪声，衰减，和眼图。(This is substantially the Matlab simulation original code, the function is to verify the absence of inter-symbol interference conditions, contains a rolloff filter, mixed noise, attenuation, and eye diagram.)

这个是matlab里基于维纳滤波算法对模拟运动模糊并加入高斯噪声的图像进行复原的程序 (This is where Wiener filtering algorithm matlab simulation of motion blur and add Gaussian noise image recovery program based on conduct)

说明：  这个文件夹里包括有计算分数阶混沌的几个算法，对于用matlab进行分数阶混沌的研究很有帮助。(This folder includes the calculation of the number of fractional order chaotic algorithms, for use matlab to the study of fractional Chaos helpful.)
