【实例简介】算法采用斜帐篷混沌映射函数初始化种群"在每次迭代中为每个个体分别产生满足正态分布!柯西分布的杂交概率和满足正态分布的缩放因子"并且记录成功变异个体的杂交概率和缩放因子"引入统计杂交概率"采用两种策略自适应地更新杂交概率。

Unicode串口通信Demo，文件太大我把编译的删除了，请自己编译，用23串口连接试试效果。

S7 200 OPC Server V1.0 PC Acceess 包含SP3

802.11a matlab源码，很详细的仿真了802.11a的数据流程

图像去噪，里面包括了中值滤波、均值滤波、混合滤波等代码，还考虑到硬件便于实现，进行了字节对齐，效果不错的

基于AT89C51单片机控制的双闭环直流调速系统设计，很好的资料，可以多多借鉴，主要是关于proteus仿真的
