program for ofdm symbol

通过matlab实现最大类间方差,根据迭代选择阈值法原理编写.(Through matlab maximum between-class variance, according to the iterative threshold selection method works written.)

SPIHT-set partitioning in hierarchical tree algorithm. it is also used for compression. here list of insignificant pixels, list of significant pixels, list of significant sets

断层序列图像的层间插值代码，matlab环境下的代码，超简单的哦~( The interpolation of two pictures.)

说明：  常用函数的汇总，有利于日常编程使用，用到某个函数时，可以直接整段截取(Common function)

说明：  做实验的一些心得体会，愿大家有所受益很好，欢迎大家学习，交流！(verygood！let we see！verygood！let we see！verygood！let we see！verygood！let we see！verygood！let we see！)

ofdm implementation with noise(AWGN)

基于转速和磁链双闭环的异步电机调速系统，采用空间矢量调制，开关周期10KHz，电网电压380V，转矩最大达30N.m(Based on double closed loop speed and flux of the induction motor speed control system, using space vector modulation, switching cycle 10KHz, grid voltage 380V, maximum torque of 30N.m)

emd.m经验模态分解的程序，这个是学习希尔伯特黄变换（hht）的重要部分(emd.m EMD program, this is the study of Hilbert-Huang Transform (hht) important part of the)
