实现小波3级分解 构建3维跨频带矢量 然后LBG聚类 再重构原图像(Construction of wavelet decomposition to achieve three inter-band 3-D vector and then reconstruct the original image LBG clustering)

说明：  Linearity in the mathematical sense is more than a straight line graph. In the jargon, it means additive and homogeneous.

一款很好用的MATLAB程序,运行会可以从清楚 的图形中看到结果(A good use of MATLAB procedures, will run from clear to see the results of graphics)

transformed sec2time in matlab

该程序主要说明直扩系统抑制正弦干扰方面的有效性。绘出不同幅度的正弦干扰信号及无干扰时的误码率.( This procedure mainly showed that expands the system to suppress the sine disturbance aspect straight the validity. Draws the different scope the sine unwanted signal and does not have when the disturbance error rate. )
