AR模型参数确定后计算出功率谱, 用Levision_Durbin 算法(AR model parameters were calculated to determine the power spectrum, using Levision_Durbin algorithm)

说明：   根据运动合成原理建立了轻质杆在斜抛(包括竖直上抛)运动中质心和端点的运动方程，用动画演示了质心的斜抛运动和两个端点的运动轨迹，并显示了杆在一定时刻的位置。(Established in accordance with the composite theory of the movement in oblique light pole throw (cast on the vertical) movement of the centroid and the equation of motion of the endpoint, animation demonstrates the trajectory of the centroid of Projectile Motion and the two endpoints, and shows the lever in a certainthe location of the moment.)

用matlab实现画出基本概率密度函数的相位，能量，实部等的功能(Using matlab to achieve basic probability density function of the draw phase, energy, real function of such)

这是用matlab编写的十进制的实数编码遗传算法程序(This is a coded real coded genetic algorithm written in MATLAB)

本程序在Matlab R2008的Simulink中实现了使用costas环对同步载波的提取，同时可提取出基带信号。(The program Matlab R2008 implements the use of Simulink to the synchronous carrier costas loop extraction, at the same time extract the baseband signal.)

说明：  自己编制的直接相关函数，用来计算信号的自相关和互相关。(Prepare its own direct correlation function, used to calculate the signal autocorrelation and cross correlation.)
