| 摘 要： | The complexities of the marine environment and the unique characteristics of underwater channels pose challenges in obtaining reliable signals underwater, necessitating the filtration of underwater acoustic noise. Herein, an underwater acoustic signal denoising method based on ensemble empirical mode decomposition(EEMD), correlation coefficient(CC), permutation entropy(PE), and wavelet threshold denoising(WTD) is proposed. Furthermore, simulation experiments are conducted using simulated and rea...
