To Calculate QOS and how it affects Security

多项式拟合，对一群散点，采用最小二乘法进行多项式拟合(Polynomial fitting, a group of scattered points, using the method of least squares polynomial fitting)

用于求解半导体激光器的速率方程，方法简单。(Used to solve the semiconductor laser rate equations, the method is simple.)

JP2INFO Get information about the image in a JP2 or JPC file.This function returns a structure holding information about a JPEG 2000 image file.

在matlab环境下，实现了用sweldens算法对一维信号作分解和重构的程序(In the matlab environment, achieved by sweldens algorithm for one-dimensional signal decomposition and reconstruction procedure)

脉冲宽度调制（PWM）是英文“Pulse Width Modulation”的缩写，简称脉宽调制。它是利用微处理器的数字输出来对模拟电路进行控制的一种非常有效的技术，广泛应用于测量，通信，功率控制与变换等许多领域。一种模拟控制方式，根据相应载荷的变化来调制晶体管栅极或基极的偏置，来实现开关稳压电源输出晶 体管或晶体管导通时间的改变，这种方式能使电源的输出电压在工作条件变化时保持恒定。　　脉冲宽 (Pulse width modulation (PWM) is the English " Pulse Width Modulation" acronym, or pulse width modulation. It is the use of the microprocessor to the digital output of analog circuits for the control of a very effective technology, widely used in measurement, communications, power control and many other fields with the transformation. An analog control means, in accordance with the corresponding changes in load modulation transistor gate or base bias, switching power supply to achieve the output transistors or transistor on-time changes in power in this way can the output voltage in the workplace conditions of constant change. Pulse width)

实现通信原理上的PCM（脉冲编码调制）调制与解调等 功能(MATLAB PCM)

说明：  FIR滤波器的设计，刚开始用matlab的可以参考下，(FIR filter example,those who just begin to learn matlab can refer to these programs.)

说明：  直扩信号BPSK的仿真，采用异或移位的算法实现PN码达到扩频的目的(BPSK DS signal simulation, using different algorithms, or shift the PN code to achieve the purpose of spreading)

一种噪声辅助数据分析方法,有借鉴意义哦，针对EMD方法的不足。( A noise auxiliary data analysis method, There are reference Oh, For lack of EMD.)
