denoising image with DWT

包含多种定位算法，如质心定位、DV-hop、APIT、三角形定位，网格定位等。(Includes various localization algorithms,for instance,centriod,APIT,DV-HOP,Grid Scan.)

说明：  两种对二阶系统进行参数辨识的最小二乘算法，一种可以直接得到输入输出之间的传递函数，一种可以解出线性的差分方程各系数，再反解得到传递函数。附带的一个二阶系统的模型，可以自行下载导入输入输出数据进行试验。(Two kinds of least square algorithm for parameter identification of second-order system, one can directly get the transfer function between input and output, the other can solve the coefficients of linear difference equation, and then get the transfer function by inverse solution. The attached model of a second-order system can download the input and output data for test.)

自编直方图均衡化程序 (Self histogram equalization program)

2009 Online blind image deconvolution for astronomy 源代码，多通道反卷积处理图像，远算速度比较快(2009 Online blind image deconvolution for astronomy source code, multi-channel deconvolution process images far faster calculation)

此源码程序是自适应滤波中的应用LMS算法进行仿真。对LMS算法的性能 收敛速度进行了研究(The source process is the application of adaptive filtering LMS algorithm simulation. The performance of the LMS algorithm convergence rate have been studied)

说明：  算谐振频率的一个小程序，并结果附图，很有参考价值(Operator resonant frequency of a small program, and the results of drawings, of great reference value to)

非线性曲线拟合是已知输入向量xdata和输出向量ydata，并且知道输入与输出的函数关系为ydata=F(x, xdata)，但不知道系数向量x。今进行曲线拟合，求x使得输出的如下最小二乘表达式成立： min Σ(F(x,xdatai)-ydatai)^2(Nonlinear curve fitting is a known input and output vectors xdata vector ydata, and know the relationship between the input and output functions for ydata = F (x, xdata), but do not know the coefficient vector x. As least-squares curve fitting expression today, find x such that the output of the establishment: min Σ (F (x, xdatai)-ydatai) ^ 2)

QPSK通信系统的Monte Carlo仿真，采用汉明码，呈现了编码信号与未编码信号在随机信道中的传输(QPSK communication system Monte Carlo simulation, the use of Hamming codes, showing a coded signal and the signal is not encoded in the transmission of random channel)
