单径或多径瑞利衰落信道仿真，基于小波变换的数字水印算法matlab代码，采用热核构造权重，主要为数据分析和统计，这个有中文注释，看得明白，音频信号通过LM386放大。

谱元法（sem)学习程序之一，用于对各类波场的模拟计算(Spectral element method (sem) to learn one of the procedures for various types of wave field simulation)

说明：  matlab数字滤波器设计,计算出参数便于dsp实现bp-ac01(matlab digital filter design, easy to calculate the parameters dsp achieve bp-ac01)

用MATLAB实现的分形蕨类植物,这个程序将永远运行下去,直到停止关闭为止。(MATLAB implementation of the Fractal Fern.This version runs forever, or until stop is toggled.)

"1D FDTD solution for open boundary in a unitless domain with a Courant factor > 1 (Unstable solutions leading to blow-up)"

资源描述用于遥感图像分类k-mean聚类方法（原理及matlab程序），笔者精心编辑的代码。

拟合和插值的matlab例程，包括多项式的拟合和插值(polynomial fitting and interpolating based on matlab)

光点识别程序，自己编写。包含javarobot类调用鼠标。打开程序后，运行。用发光物体如手机在自带摄像头前控制鼠标移动。程序有抗干扰处理，能屏蔽外部光线的影响。(Spot recognition program, write your own. Contains javarobot class called mouse. After opening the program, run. Comes with a shiny object in front of the camera to control mouse movement such as mobile phones. There are anti-jamming processing program that can shield the influence of external light.)

LDPC编码，BPSK调制，AWGN信道，译码，可以仿真出误码率曲线(LDPC coding, BPSK modulation, AWGN channel decoding, the BER curves can be simulated)
