多尺度分析於環境量測信號與雜訊分離之應用

摘要


環境量測信號經常遭遇外在雜訊的干擾,諸如量測電纜線受電磁干擾及遙測信號解調失眞等,而使眞實量測信號與雜訊混淆。因此,信號後處理必須先將信號與雜訊分離,避免雜訊嵌入信號分析頻譜中而誤導分析結果。本文研究目的爲為利用小波理論中的量測信號多尺度表現方法,探討多尺度分析於環境量測信號與雜訊分離技術之可行性。

Environmental measuring signals are often interfered by exterior noise which always resulted from the EMI or decoding distortion of telemetry. To avoid the misreading of analyzed results, the de-noise processing of measured signals have to be fulfilled before analyzing procedures. In this paper, the multiresoultion analysis of wavelet theory will be applied to recover the measured signals and to decrese the influence of exterior noise.
