Matlab-FFT

利用matlab产生二进制调制信号波形，以实现噪声信号干扰研究(Matlab generated using the binary modulation signal waveform in order to achieve noise signal interference study)

说明：  边缘检测程序，有各种边缘检测算子，包括sobel等，自己写的源程序，共享(Edge detection process, a variety of edge detection operator, including sobel and so on, to write the source code, sharing)

This is Room Impulse Response.Everybody can download it to discuss.

Optimization technic of Least Square

本程序为粒子群算法的源代码可应用于微电网的多目标经济优化调度(This program is the source code of particle swarm optimization algorithm and can be applied to multi-objective economic optimal dispatch of microgrid)

这个是一个倒立摆的控制设计程序，用 c写的可执行文件(This is an inverted pendulum control design procedure)

用VITEBI算法对信道输出解码。这个算法既能用于卷积码的软判决解码，也能用于硬判决解码(failed to translate)

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.
