CDMA的matlab仿真CDMA的matlab仿真CDMA的matlab仿真(simulation of CDMAsimulation of CDMAsimulation of CDMA)

matlab调用计算机声卡，实时显示计算机播放的声强级，使用数据获取工具箱，强烈推荐(call matlab computer sound cards, real-time display of the computer to play sound intensity level, the use of data acquisition toolbox, strongly recommend)

说明：  关于SAR成像的BP算法 关于SAR成像的BP算法(A very good BP imaging algorithm)

本程序用于对干涉条纹进行滤波，二值化，骨骼化，最后为求得条纹间距而得到一个像素宽度的图像(This procedure is used to filter the interference fringe, thresholding, skeletonization, and finally to obtain the fringe spacing and width of the image by one pixel)

主要介绍了七单元线形天线阵的波达方向估计（DOA）(Introduces the seven cell linear antenna array direction of arrival estimation (DOA))

QPSK信号通过瑞利衰落信道后的误比特率和误符号率，并与AWGN信道下的误比特率和误符号率进行对比。其中，多普勒频移为 100Hz，经过矩形脉冲成形后的抽样时间间隔为1/800000s。(The QPSK signal harms the bit rate after the Rayleigh fading channel and harms the mark rate, and harms the bit rate with the AWGN channel under and harms the mark rate to carry on the contrast. And, the Doppler shift is 100Hz, after undergoing the square pulse forming the sampling time gap is 1/800000s. )

说明：  基于模型预测控制算法做自动驾驶车辆跟踪圆型轨迹例程(Using model predictive control algorithm to track circular trajectory of autonomous vehicle)

说明：  这是语音信号处理里面的，基本谱减法，处理的效果很不错，很适合初学者研究！(This is the speech signal processing inside the basic spectral subtraction to deal with the effect of very good, very suitable for beginners study!)

2D FFT and 2D IFFT in matlab. inputs are original data and block size. ex) block size = [8 8]
