说明：  图像处理中将极坐标转换为笛卡尔左边的几个调用函数，包含bin,density 和ffgrid(in the image process,please convert the polar coordinate into castinate coordinate, there are some diaoyong functions ,include bin,density and ffgrid)

viterby algotitm with soft input . a good simulation in mathlab

说明：   在高阶谱分析工具箱是一个M文件集合实施了多种先进的信号处理算法的频谱估计，polyspectral估计，时频分布计算，并包含许多实际应用如时延估计，谐波恢复，参数估计的Volterra（非线性）模型，以及自适应线性预测。其他潜在的应用包括音响，生物医学，经济学，地震勘探，无损检测，海洋学，等离子体物理，雷达，声纳，语音等(The Higher-Order Spectral Analysis Toolbox is a collection of M-files that implement a variety of advanced signal processing algorithms for spectral estimation, polyspectral estimation, and computation of time-frequency distributions, with applications such as time delay estimation, harmonic retrieval, parameter estimation of Volterra (nonlinear) models, and adaptive linear prediction. Other potential applications include acoustics, biomedicine, econometrics, exploration seismology, nondestructive testing, oceanography, plasma physics, radar, sonar, speech etc. )

Its a method where we have used wavelet and svd method to estimate the age of digital fingerprint using knn clustering method.

nonlinear switching systems 仿真(nonlinear switching systems)

8psk in Rayleigh fading

说明：  简单眼图，适用于初学者，仅仅是简单的代码，高手请绕道(Simple eye)

应用sift算子进行图像匹配，效果不错。。。(sift is used to match two picture，the result is good...)

fft算法matlab实现，可直接运行，对比给定波形和经过fft后的波形效果(fft algorithm matlab realize, can be directly run, compared to a given waveform and waveform effects after fft)

说明：  这是基于帧差法对运动目标检测的代码 希望对大家有用(This is based on frame difference of the moving target detection code)
