这是一个完整的ofdm系统仿真matlab程序，给出了同步算法，包括定时估计和频率估计算法的仿真(This is a complete OFDM system simulation matlab procedures, given synchronization algorithm, including timing and frequency estimation algorithm is estimated that the simulation)

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.)

第一：边界加强，通过估计噪声和实际信号的比值，来确定各个尺度的细节系数，以达到噪声抑制和边界加强。第二，通过对小波分解的近似部分进行直方图均衡，达到加大整幅图片的对比度，而不太影响细节的目的。(First: to strengthen the border, through the estimates and the actual signal noise ratio, to determine the details of each scale factor, so as to achieve noise suppression and boundary strengthening. Secondly, the wavelet decomposition of the approximate portion of histogram equalization to increase the contrast of the whole images, and do not affect the details of the purpose.)
