基于MATLAB,各种信道的估计方法，共13种(Estimation_of_Kinds_of_Channels(MATLAB))

security in cloud based applications papers

this is basic matlab explanation. i will upload 5documents.

关于OFDM信道估计算法的仿真，比较详细(Simulation of channel estimation on OFDM)

自动生成伪随机码，画图说明产生的三组伪机码，将三组伪随机值存放到新矩阵并传送到Workspace中，方便以后调用数据(Automatic generation of pseudo-random code generated drawing shows three sets of pseudo-machine code, the three groups of pseudo-random value is stored into a new matrix and sent to the Workspace, the call data to facilitate future)

说明：  带有收缩因子和惯性权重的基本PSO粒子群算法源代码。本源代码模块化编写，结构清晰，便于改进和做数值实验 (With the shrinkage factor and the basic PSO inertia weight particle swarm algorithm source code. Modular source code written in a clear structure, easy to improve and to do numerical experiments)

三电平SVPWM控制算法的中点控制方案的解决方法(Solve method for point control algorithm of three level SVPWM. )

求希尔伯特变换后的瞬时频率,经过信号的解析，反正切变换，求导得出(instant frequency)

一种基于区域活动轮廓模型，通过引入局部的图像拟合能量来提取图像的局部信息，能够有效的额分割强度不均一的图片。较传统的水平集方法有更少的计算量(By introducing the local image fitting(LIFenergy to extract the local image information,our model is able to segment image with intensity inhomogeneities.)

M-K法在水文中有着广泛的应用，主要用于时间序列的突变点检验。(MK method has been widely used in hydrology, the main point of testing for mutations in the time series.)
