自相关程序，本程序用来求序列的自相关运算，效果不错(since the associated procedures, the procedures used for the sequence-related operations since good results)

这是一个小波包，可以用来分析时间序列。里面包括降噪程序和时间序列预测程序。(This is a packet, can be used to analyze the time series. Procedures which include noise reduction and time series prediction procedures.)

一维EKF滤波算法 主要用于目标跟踪 同理可推广到多维情况(ekf object tracking)

说明：  基于小波变换模极大的多尺度图像边缘检测matlab源代码，该算法采用的是样条小波，为了更好的检测边缘，用多孔算法代替了mallat算法。该算法和mallat快速算法主要区别： 1 多孔算法不需要抽取偶数样本，所以奇异检测定位更准确，相应的重构是不需要插零。2 多孔算法需要对滤波器进行伸缩。(based on wavelet transform modulus maxima of multiscale edge detection Matlab source code, The algorithm used is kind of wavelet, in order to better detect the edge of porous algorithm instead of Mallat algorithm. The algorithm and fast algorithm Mallat major difference : an algorithm porous not even take samples So singular position detection more accurate, the corresponding Reconstruction interpolation is not zero. Two porous algorithm need to filter extendable.)

　数字信号处理的主要研究对象是数字信号，且是采用运算的方法达到处理的目的的(The main digital signal processing research object is a digital signal, and the method of operation is used to achieve the purpose of processing)

作为一个有吸引力的技术， 减轻多径干扰的正交频 分复用（OFDM）已经被广泛应用 在各种广播系统，诸如数字 视频广播（DVB）系统。尽管它的竞争力 属性，OFDM信号的特点是非常高的 峰值对平均功率比（PAPR）的水平。( As an attractive technique in mitigating the multipath interference, Orthogonal Frequency Division Multiplexing (OFDM) has been widely applied in various broadcasting systems such as, the Digital Video Broadcasting (DVB) systems. Despite its competitive attributes, OFDM signals are characterized by very high Peak-to-Average Power Ratio (PAPR) levels.)

Implements PSO for function optimization for different standard mathematical functions.

说明：  线性自抗扰通过sfunction实现，适用于基础入门学者。(Linear auto-disturbance is achieved through sfunction,For basic entry scholars.)

Beam propagation method code in Matlab.

说明：  代码完成的功能是OFDM的仿真，可以显示误码率以及各路波形和星座图(The function of the code is OFDM simulation, which can display the bit error rate, waveform and constellation)
