| Abstract: | This paper makes a research on technology of time domain reflected signal detection and pretreatment based on cable system. The error is large using wavelet transform to analyze singularities of time domain reflected signal of cable system and conduct detection and pre-treatment. The article puts forward self-adaptive certain function algorithm based on the optimal decomposition level of wavelet transformation using reflected wave de-noising technology of wavelet tmalysis. |
