说明：  matlab平台，生成雷达回波信号的仿真程序(Radar echo signal generation simulation program, matlab platform)

This is an example of SPIHT coding

独立成分分析的matlab实现，适合初学者学习和使用(Independent component analysis matlab implementation, suitable for beginners to learn and use)

leach协议簇头选择算法的改进及仿真 在改进的LEACH．H协议在簇头节点的选举过 程中，充分考虑了簇头节点剩余能量因素，设定了簇头的能量阀值，防止了低能量的节点成为簇头。在此基础上引 进簇头调整过程，该过程通过排除紧密邻居簇头和增加必要的簇头，在一定程度上解决了LEACH协议存在的问题， 从而达到均衡网络能量消耗，延长生存期的目的。网络仿真证明了新算法的可行性。 (An Improved Algorithm for Selecting Cluster-heads in LEACH)
