简单的热释电红外传感器电路及制作

本文介绍了数字喷泉码原理，详细讨论了随机线性喷泉码、LT码和RAPTOR码编译码原理及实现方法，针对LT码仿真验证了数字喷泉码在删除信道的性能。

基于labview的 振动信号数据采集，希望对大家有所帮助

该系统是一个数据库管理系统，当今数据库系统的开发工具种类非常多。常用数据库开发工具有面向对象的如:Informix-4gl, C,Pascal语言;有面向过程的如 visual foxpro,visual basic,还有web方式的如: asp.jsp与数据库的连接。

pca降维，直接运行，你把你里面的数据换成你自己的就可以啦，注意里面的注解，欢迎下载，你指的拥有，可以的话，欢迎打分，谢谢！

利用经验模态分解提取IMF向量与残余向量的matlab程序，可以直接运行emdplus.m，亲测有效，不能运行不要钱~，主函数与样本熵函数samp经过了分析，里面有详细注解，EMD.m函数用的歪国人写的的~目前也是较为常用的版本了

用于计算小波及小波包分解时的香农熵，以便确定是否所选择的小波基是否是最优的！
