小波去噪,利用小波系数在相邻尺度上的相关性关系,针对小波系数估计中硬阈值方法和软阈值方法的缺点,
通过对双重量收缩函数得到的阈值乘以一个合适系数进行修定的折衷方法,提出了一种新的小波域局部自适应去噪算法.实验结果表明,该方法既可以去除噪声,又可以较好地保留图像的高频细节特征.(Wavelet denoising using the wavelet coefficients in adjacent scales of the correlation relationship between the estimation of wavelet coefficients for the hard thresholding and soft thresholding shortcomings, through the contraction of the double weight of the threshold function has been multiplied by a suitable coefficient revised compromise, proposed a new wavelet-domain partially adaptive denoising algorithm. The experimental results show that the method can remove noise, also can be used to retain the details of the characteristics of high-frequency images.)

循环冗余码的生成和验证:数字通信中的编码分为信源编码和信道编码两大类。为了提高数字通信的可靠性采取的编码称为信道编码,又称抗干扰编码。数字通信中为了尽可能地提高通信的可靠性,需要采用信道编码技术,对可能或已经出现的差错进行控制,CRC码就是其中的一种编码技术。本实验就是编写RCR编码,可以模拟发送信息,噪声加入,检测验证,信息重发的过程!(Cyclic redundancy code generation and validation: digital communication in the coding is divided into source coding and channel coding two broad categories. In order to improve the reliability of digital communications to the code known as channel coding, also known as anti-interference codes. Digital communication as much as possible in order to improve the reliability of communication need to use channel coding techniques, which may or may control the errors that have emerged, CRC code is one of a kind of coding techniques. RCR in this experiment is to write code that can simulate send a message, noise adding, testing verification, information, process re-issued!)
