分析并实现了跳频信号的检测方法，用程序给出仿真结果(Analysis and implementation of frequency hopping signal detection method, using the program simulation results)

calculate group delay

说明：  运用单纯形法的改进型布谷鸟算法，效果优良(Improved cuckoo algorithm using the simplex method)

Neighborhood rough set based feature evaluation and reduction

used to filter the latent state variable(this file is used to filter the latent state variable)

Traditional police boundaries—precincts, patrol districts, etc.—often fail to reflect the true distribution of criminal activity and thus do little to assist in the optimal allocation of police resources. This paper introduces methods for crime incident forecasting by focusing upon geographical areas of concern that transcend traditional policing boundaries.

simple IDMA TYPE RANDOM INTERLEAVER

多径效应的时域表示实际上就是不同路径来的信号存在随机的时延差。对于抗其它扩频信号干扰性能，及抗多址干扰性能。我们这里考虑简单的情况，只考虑一个用户干扰的情况，说明其具有抗多址干扰性能就行。(Multipath effect is actually a time domain representation of the signal path to the existence of different random time delay difference. Other spread spectrum signal for the anti-interference performance, and anti-MAI performance. Here we consider the simplest case, considering only one user interference, indicating its performance with anti-multiple access interference on the line.)

EM algorithm based on constrained mixture Gaussion model

说明：  4个纹理分割算法合集+n篇IEEE论文合集 对研究纹理分割的同学来说，很有效(4+ n texture segmentation algorithm Collection collection of research papers IEEE paper texture segmentation students, it is very effective)
