摘要
本文根据傅立叶分析和重抽样理论讨论了关于过抽样信号恢复的处理方法 ,所提出的重抽样信号恢复平均法对于强噪音背景下弱信号的提取 。
This paper discusses processing methods for oversampling signal recovery by Fourier analysis and theory of replicate sample. The average method of replicate sample recovery signal is presented. Its effectivity is obvious for signals with high noise.
