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。(Poincare mapping sections in the phase space properly (should be beneficial to observe the system and changes in movement characteristics, such as the cross-section can not be tangent trajectory, but also can not contain rail line) to select a cross-section, in this section for a total of conjugate variables, such as x1 and X.1 take a fixed value, call this cross-section for the Poincare section, the phase space of the continuous trajectory of the point of intersection with the Poincare cross-section to become cut-off point.)

After identifying the best MNT− 1 nodes with the simplified branch metric and the accumulated branch metric at stage NT − 1, we then calculate the LLR of each coded bit utilizing the standard squared Euclidian distance metric. The log-likelihood ratio (LLR) of a posteriori probability (APP) of each coded bit conditioned on the received signal y is normally calculated using the max-log approximation.
