将小波相邻系数相关性的降噪思想引入到冗余第2代小波中，提出了基于邻域相关性的冗余第2代小波降噪方法，该方法克服了传统阈值降噪没有考虑小波系数之间相关性的不足。(Aiming at fault feature extraction in the background of strong noise, a wavelet denoising idea by incorporating neighboring coefficients is introduced into redundant second generation wavelet case. A denoising method of redundant second generation wavelet using neighbor dependency is presented. It overcomes the deficiency of traditional thresholding approaches. In this method, an original signal is decomposed by redundant second generation wavelet, and the detail and approximation signals have the same length as the original signal. The detail signals at each scale are then processed by neighbor dependency. Finally, the approximation signal and processed detail signals are reconstructed by inverse transform of redundant second generation wavelet to realize the signal denoising. )

程序给出了边缘检测及轮廓跟踪的一般方法,其是基于matlab来编写的!(procedures given the edge detection and tracking of the general contour method, is based on Matlab to prepare!)

说明：  该程序是一位同学写的，运行该程序需要rtlSDR设备，便宜一点的淘宝不到100元，插上rtlsdr后，配置好matlab环境，能够实现扫描25M-1.75GHz的当地频谱，当然也可以自行修改范围(rtlsdr rx specsweeep 25MHz~175MHz)

用两种向量化和一种循环的思路计算水仙花数，并给出所需时间比较 水仙花数是指一个三位数,其各个数的立方和等于该数(Quantified in two and a loop to the idea of calculating the number of daffodils and narcissus are given the time required for comparison is a three-digit number, the individual cubes, and equal to the number of)

说明：  simulink 通信仿真手册 里面详细介绍了每个模块的作用和详细参数设置(communication simulation simulink Manual which details the role of each module and detailed parameters set)
