用Matlab仿真直接序列扩频系统,M文件编译，附带PPT说明(Matlab simulation with direct sequence spread spectrum system, M files to compile, with notes PPT)

本文件为本人学习matlab编成期间的部分笔记内容，都是比较重要的知识点和初学者十分容易出错或者十分困惑的问题。包括函数的重要概念，GUI回调语句中的引号问题，点运算等等。()

this code uses the particle swarm optimization PSo techinque in tunning a PID controller in order to obtain the adequate values of the controller gains

摘要:提出了一种新型的人工免疫算法用来解决多目标函数优化问题。基于自然免疫系统固有的优良特性对算法进行了设计和分析。 最后,算法对3个较复杂的多目标问题进行了优化,优化结果能很好地覆盖问题的Pareto最优面,并且把算法与某些混合遗传算法进行 了对比实验,表明人工免疫算法在解决多目标优化问题上具有可观的研究前景。 (Abstract:In order to effectively solve multiobjective optimization problems, a novel artificial immune algorithm is proposed. It is de signed and analyzed based on excellent intrinsic features of nature immune systems. Additionally, the algorithm sensitivity to its tuning pa rameters is briefly assessed. Finally, the algorithm is applied to solve three complex multiobjective optimization problems and the results ca perfectly map the Pareto-optimal fronts. By comparing the algorithm with some genetic algorithms, it shows the good prospect to apply ar tificial immune system to solve multiobjective optimization problems. )
