基于粒子群算法的多目标搜索算法，基于matlab仿真源程序代码，用于学习matlab算法设计的一个很好的例子(Multi-objective search algorithm based on particle swarm optimization algorithm, based on the Matlab simulation source code for a good example to learn matlab algorithm design)

遗 传 算 法 的 简 明 案 例 非常适合初学者应用(The Genetic Algorithm condensed case)

说明：  webrtcd的aec模块的matlab实现，包括了频域NMLS滤波以及后期的非线性处理部分。可以得到较好的回声消除效果。(Matlab implementation of AEC module of webrtcd includes frequency domain NMLS filtering and later non-linear processing. A better echo cancellation effect can be obtained.)

建立Jakes模型，生成Rayleigh信道。以此为基础，研究不调制，及DSPK等方式的调制下，均衡技术（尤其是迭代均衡）的给误码性能带来的增益。(To build the Jakes model,we can get the Rayleigh channel,on the basis of which we study on the benefit of equilization(Iterative equilization specially) in DSPK modulation.)
