摘要
分析了文献 [1 ]中分段多项式的光滑性 ,给出了分段多项式在节点处光滑的相容条件 .并通过对输入信号的光滑重构的方法 ,对文献 [1 ]算法进行了改进 .
The smoothity of piecewise polynomial appl ie d in literature \ is discussed, and the consistency condition is given such that the piecewise polynomial is smooth in its nodes. The method of literature \ is improved by signal reconstructing smoothly. Finally, a simple example i s given to show effectiveness of signal smooth reconstruction.
