科斯塔斯环提取8PSK调制载波 Demod 8Psk

本程序在matlab环境下，基于粒子群算法对pid控制器进行优化控制,从而完成性能更优(The program in matlab environment, based on particle swarm optimization algorithm pid controller to control, thus completing the better performance)

一、实验要求 信号为两个正弦信号加高斯白噪声，各正弦信号的信噪比均为10dB，长度为N，信号频率分别为和，初始相位，取，取不同数值：0.3，0.25。为采样频率。分别用Levinson递推法和Burg法进行功率谱估计，并分析改变数据长度、模型阶数对谱估计结果的影响。(Power spectrum estimation)

编写了利用MATLAB计算任意桁架的静力分析，得到各杆的应力和各结点的位移，并画出变形前后的桁架图(The static analysis of arbitrary truss is made by using MATLAB, the stress of each rod and the displacement of each node are obtained, and the truss diagram before and after deformation is drawn)
