说明：  实现FSK调制的详细过程，对学习很有帮助，必须顶(Detailed process to achieve FSK modulation, useful for learning to be top)

此源文件包含了MATLAB两种自相关函数，并将其用于数字信号的处理，比较两种函数的不同(This source file contains two autocorrelation functions of MATLAB and is used for digital signal processing, comparing the two functions.)

这是一个关于PSO与PID相结合起来的一个程序,其主要用于它的延时用.(This is a study on the combination of PSO with the PID to a process, its main use for its delay.)

用matlab做方差分析的几个例程包括：单因素一元方差分析，双因素一元方差分析 非参数方差分析(ANOVA using matlab to do a few routines include: single-factor analysis of variance one yuan, two-factor analysis of variance one yuan non-parametric analysis of variance)

In this paper, the concepts of Daubechies wavelet transform are discussed. The Daubechies wavelets are a family of orthogonal wavelets defining a discrete wavelet transform and characterized by a maximal number of vanishing moments for some given support. With each wavelet type of this class, there is a scaling function which generates an orthogonal multi resolution analysis.

TKK Voice Source Analysis and Parametrisation Toolkit (Aparat) is a voice inverse filtering and parametrisation software developed at Helsinki University of Technology (TKK) Acoustics and Audio Signal Processing Laboratory, Espoo, Finland. It is especially useful in rapid inverse filtering and parametrisation of large amounts of pre-segmented vowels.

对于持续时间为500s的两个LFM信号，其初始频率分别为0.1Hz、0.3Hz，中止频率分别为0.3Hz、0.1Hz，在不含噪声和含有噪声（ ）的情况下，仿真(for the duration of the two 500s LFM, the initial frequency of 0.1Hz. 0.3Hz, suspension frequencies of 0.3Hz, 0.1Hz. In noise-free and noisy () cases, the simulation)

电力线通信多径信道模型-Manfred Zimmermann模型，多径效应的传递函数H(f)可以用N条传输路径的叠加以及含有频率f、延时τ、距离d的方程来表示： H(f)=∑g_i *A(f,d_i )*e^(-j2πfτ_i ) 式中，i 为路径号， g_i为路径 i的加权系数(包含了传输系数和反射系数的作用)，A(f,d_i )为衰耗，其大小由长度、频率决定，τ_i是每条路径上的延时。 (Powerline Communication multipath channel model-Manfred Zimmermann model)
