這是 GA 的改進版演算法，最大的差別在於能保證每次選出的基因都是更好的(GA improved version of the algorithm, the biggest difference lies in its ability to ensure that each of the selected genes were better)

we shed light on the potential and implementation of index modulation (IM) techniques for MIMO and multi-carrier communications systems which are expected to be two of the key technologies for 5G systems. Specifically, we focus on two promising applications of IM: spatial modulation (SM) and orthogonal frequency division multiplexing with IM (OFDM-IM), and we discuss the recent advances and future research directions in IM technologies towards spectral and energy-efficient 5G wireless networks.

说明：  观察数据长度N的变化对DTFT分辨率的影响 这几个程序是老师写的 对于理解DTFT有很大帮助(Effect of observation data length N on DTFT resolution These programs are written by the teacher and are very helpful for understanding DTFT.)

说明：  用matlab编的语音增强的一个程序，是用维纳滤波实现的，(Matlab made use of a speech enhancement procedure, Wiener filter is used to achieve,)
