EEMD-IF Based Method for Underwater Noisy Acoustic Signals Enhancement in Time-Domain

This paper introduces a novel signal enhancement method to mitigate the effects of underwater acoustic ambient noises. The combination of ensemble empirical mode decomposition (EEMD) and iterative filtering (IF) is adopted to analyze the underwater speech and chirp noisy signals. The main novelty re...
