NeuralNetwork_BP_Classification

描述在matlab环境下，bch的误码率，仿真给出了在编码情况下的误码比较，可以清楚的得出bch码的编码增益。(Describes the matlab environment, bch the BER, the simulation is given in case of error in the code comparison can be drawn clearly bch code coding gain.)

实现图像的DCT高通、低通滤波器并与傅里叶变换做比较.有图可见，经DCT低通滤波后，图像变得很模糊。因为DCT是FFT取其实部，能量减少，因此图像变得很模糊，没有经FFT滤波后的效果好。 经DCT高通滤波后的图像： 经DCT高通滤波后，图像的低频部分被滤除掉，图像变黑，只有边缘的痕迹可见。 (The DCT of image high-pass, low pass filter and compared with the Fourier transform.)

以循环的方式随机选择簇头节点，将整个网络的能量负载均匀分配到网络中的每个传感器节点，从而达到降低网络能耗，提高网络生存周期的目的。(Cyclic manner randomly selected cluster head node, the energy of the entire network load evenly distributed to each sensor node in the network, which can reduce energy consumption and improve the life cycle of the destination network.)

MATLAB实现能进行边缘检测，在生活中有很重要的应用(MATLAB implementation capable of edge detection, in life there are important applications)

matlab与C的混编，处理乘性噪声，建立M次开根号模型，需要调整参数。(written with matlab and C by S. Yun and H. Woo, "A new multiplicative denoising variational model based on m-th root transformation".)

说明：  与论文Generalized Sparse Covariance-based Estimation对应的程序(The corresponding program of 'Generalized Sparse Covariance-based Estimation'.)

In this implementation of tracking a ball, we will track a live ball using Kalman filter. The tracking will switch to autorun mode when the sight of the ball is lost and Kalman will estimate the motion based on it s previous states

这个程序关于语音信号的消噪，实现了一个基于递归最小二乘法的噪声抵消器(This program about the speech signal de-noising, implements a recursive least squares method based on a noise canceller)

滤波器和信号频谱分析的MATLAB的SIMULINK仿真，不错的程序(filter and spetrum analyse)

生成数字信号处理课程常用信号：冲激、阶跃、斜坡、正弦、复指数和指数信号，幅度长度时延频率相位可控。(Signal generation, capable of generating pulse, step, ramp, sine, complex sine and exponent signals.)
