WiMax physical layer MATLAB code

this is simple qpsk for matlab code

背景提取，迭代法(Surendra算法）；即采用帧差的方法，一帧图像减去前一帧图像，即可以对比得到图像中变化（移动）的区域，扣除移动的区域，即得到不动的背景。采用多帧图像迭代的方法，得到更加准确的背景。(Background extraction, iterative method (Surendra algorithm) frame difference method is used, an image by subtracting the previous frame, which can receive the image contrast change (movement) of the area, less the area of ​ ​ movement, that is obtained immovable background. Multi-frame image iteration method, to be more accurate background.)

基于NLMS算法的回声消除，具有双端检测功能(Echo cancellation nlms Double-end detection)

2dpca的matlab源代码,很好用的一个算法，大家可以来试试啊(2dpca the matlab source code, good use of an algorithm, we can to try ah)

该函数对一个区间进行Pgama投影，返回修正的区间(the function of an interval Pgama projection, that the return interval)

对多传感器数据进行加权融合，该算法中提出来扩展支持度矩阵，用Matlab进行仿真。(Weighted multi-sensor data fusion, the algorithm proposed to extend the support matrix, using Matlab simulation.)

function [] = splitMerge(x,y) threshold = 5 0.5 meter set(1).x = x set(1).y = y set(1).check = 0 while 1 allChecked = 1 numSets = size(set,2)
