高精度磨光样条及其在信号处理中的应用

Smoothing splines with higher accuracy and their application in signal processing

该文讨论了高精度二次样条函数磨光法在一维信号处理中的应用，推导出信号的分解与综合金字塔算法．通过对模拟信号实际计算并与Ｂ－小波算法比较，该方法具有算法简单、计算速度快、无失真恢复、细节“量化值”小等优点．

This paper discusses the 2-degree smoothing functions with higher accuracy and their ap-plications in signal processing.The formulae for signal decomposition and reconstruction aregiven.Some numerical results are obtained which show that this method can result in fastcomputation,accurate reconstruction and small signal detail as compared with the use of B-wavelet.
