mimo的相关书籍，主要对mimo技术所涉及的一些基础理论进行概括和总结。方便读者阅读。(mimo' s books, mainly on mimo technology involved some of the basic theory Summary and Conclusion. The convenience of readers.)

使用蚁群算法并进行改进，利用改进的蚁群算法优化BP神经网络的程序(Ant colony algorithm and improved use of improved ant colony algorithm to optimize BP neural network program)

Rossler混沌系统加入控制器后，在控制器作用下在有限时间内仍然达到了镇定(Rossler chaotic system to join the controller after the controller under a limited period of time still to reach a calm)

用粒子群算法求解车间调度问题，包含甘特图的制作程序(Particle swarm optimization algorithm for job shop scheduling problem, including Gantt chart)

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.
