Noise can be defined as unwanted signal that interferes with the communication or measurement of another signal. Noise conveys information regarding the source of the noise, e.g. the noise from a car engine conveys information regarding the state of the engine.

fsk modulation Frequency shift keying (FSK) is the most common form of digital modulation in the high-frequency radio spectrum, and has important applications in telephone circuits. This article provides a general tutorial on FSK in its many forms. Both modulation and demodulation schemes will be discussed

基于simulink的直接序列扩频通信系统仿真，采用bpsk调制(Direct sequence spread spectrum communication system based on simulink simulation, using bpsk modulation)

Image Edge Extraction Algorithm Calculation of Lagrange and Newton

该源代码是本人亲自所写，使用DWT对图像可以进行三次小波分解，直接下载可以使用，对图形图像处的同行们非常有用，欢迎下载。(The source code is written by himself, the use of DWT can be three times the image wavelet decomposition, a direct download can be used in the graphic image Department colleagues very useful are welcome to download.)

这是《小波分析理论与MATLABR2007实现》的源代码。主要是基于Matlab的小波工具箱实现小波基选择、小波包分解、Mallat变换以及小波变换在边缘提取、图像去噪、数据压缩等中的应用，特别包含了二代提升小波的相关内容，理论与实际相结合。大家想要了解的二进小波、正交镜像滤波器组[QMF]等概念这里都有体现。(This is 《MATLABR2007 wavelet analysis theory and implementation》 of the source code. Mainly based on the Matlab wavelet toolbox implementation of wavelet selection, wavelet packet decomposition, Mallat transform and wavelet transform in edge detection, image denoising, data compression, such as the application, in particular, contains a second generation of relevant content Lifting Wavelet theory and reality. Everyone wanted to know about the dyadic wavelet, quadrature mirror filters [QMF] concepts are embodied here.)

调试完成的matlab仿真代码，非常好的参考(Debug matlab completed simulation code, a very good reference)
