OFDM中采用的16QAM的simulink实现(OFDM16QAM)

计算occupied bandwidth(OBW)的测试代码，在原来的基础上增加了回退修正的功能，结果更准确一些。(Test code of calculate the occupied bandwidth (OBW)，append some code to fix the result.)

由一张图像提取圆形的边缘,得到离散的点来拟合椭圆,并简单的去除噪声,得到椭圆中心坐标.(Extracted by a picture rounded edges to fit the discrete points oval, and simply remove noise, get the coordinates of the center of the ellipse.)

PSO algorithm to tuning PID

基于GA-PSO算法，包含程序和数据，还有word说明！！！(Based on the GA-PSO algorithm for prediction! ! !)

说明：  处理波形，计算声波再通过障碍物以后的延迟,从而计算声波在不同介质中的传播速度(Treatment of waveform, calculated the time delay after the sound waves pass through the obstaclesand，In order to estimate the acoustic propagation velocity in different media)

功率谱估计,包括周期图法，burg法，music法，和welch法，并绘图比较(psd,pmusic，pburg)

说明：  完整的QPSK的调制与解调，已调试通过，认真学习一下(QPSK modulation and demodulation)

用专家系统优化下面的PID参数或设计一个专家控制器，被控对象为 并与PI控制算法进项比较(use expert system optimization below the PID parameters, or a design expert controller, and object to the PI control algorithm with a credit comparison)
