DWT-for-LL

基于mpsk的载波恢复,有完整的simulink模型，可以观察星座图(carrier recovery of Mpsk)

these codes read input image and generate the 2D gabor filters, with changeable scale, orientation, perform the convolution with input image.

本程序实现图像LENA的压缩传感，算法采用正交匹配法 (This procedure LENA compression of image sensing, orthogonal matching algorithm)

说明：  绘制庞加莱截面图,在相空间中适当（要有利于观察系统的运动特征和变化，如截面不能与轨线相切，更不能包含轨线）选取一截面，在此截面上某一对共轭变量如x1和x.1取固定值，称此截面为Poincare截面，相空间的连续轨迹与Poincare截面的交点成为截点。(mapping Poincare section, in phase space appropriate (observation system should be beneficial to the movement and change, if not with the section line tangent track, rail lines not included) selected a cross section, in this section for a pair of conjugate variables such as x1 and X.1 from fixed value, stating that this section of the Poincare section, phase space for the track and Poincare sections of the intersection as intercept point.)
