道格拉斯-普克算法(Douglas–Peucker algorithm，亦称为拉默-道格拉斯-普克算法、迭代适应点算法、分裂与合并算法)是将曲线近似表示为一系列点，并减少点的数量的一种算法。它的优点是具有平移和旋转不变性，给定曲线与阈值后，抽样结果一定。(Douglas Peucker algorithm is the curve approximated by a series of points, and reduce the number of points of an algorithm. It has the advantages of translation and rotation invariance, given the curve and the threshold, the sampling results must.)

以往的测时间延迟的方法时利用信号相关性来求的，利用MUSIC算求两信号的时间延迟具有很高的精度。(Measurement of time delay before the method used to seek correlation signal, the use of MUSIC operators seek time delays of two signals with high precision.)

上面都是最新的LDPC编码技术，希望对大家都有用哈，我觉得十分的有用(The above are the latest LDPC coding techniques, I hope everyone Ha, I think is very useful)
