改进粒子群算法。较好的全局收敛性。较快的速度。(Improvement of Particle Swarm Optimization. Better global convergence. Faster speed.)

Implementation of fuzzy system with matlab in case of "Choosing of Study".

说明：  实现了PCM编码和译码的功能，适合各个Matlab版本运行。(Achieve a PCM encoding and decoding functions for each version of Matlab to run.)

自适应均衡领域的经典算法，最小均方误差算法（LMS）算法的数字均衡器建模源代码。建模建立了一个通信系统的收发两端，并模拟了信道衰减和噪声。并在接收端使用了数字均衡器。主程序中一次在接收端使用了自适应均衡器，另一次没有使用，可以清楚看到均衡前后误码率的差别。(The field of classical adaptive equalization algorithm, the minimum mean square error algorithm (LMS) algorithm for modeling digital equalizer source code. Modeling the establishment of sending and receiving ends of a communication system, and simulate the channel attenuation and noise. And at the receiving end using a digital equalizer. Once the main program at the receiving end using adaptive equalizer, another did not use, you can clearly see the difference before and after the equalizer BER.)

matlab生成的mat文件导入到vc++里面，方便matlab和vc联合编程，程序为最基础底层编程，已经过测试(matlab generated mat file into vc++ inside, easy matlab and vc joint programming, the program is the most basic underlying programming, has been tested)

Matlab数字信号处理工具箱 MATLAB已带有数字信号处理工具箱，但不少数字信号处理学者又发展出一些数字信号处理的函数，例如我们会常用到ideal_lp、Hr_type1、dft、idft、Circonvt、freqz_m，...等等，《数字信号处理---使用MATLAB》一书提供了这样的工具箱，内容如附图，工具箱在附件中。(Digital Signal Processing Toolbox Matlab)
