- Abstract
For non-linear and non-stationary signals, traditional signal processing methods cannot effectively capture their characteristics. For this purpose, time-frequency analysis algorithms are needed to analyze the frequency domain characteristics of the signal at different times. The traditional Empirical Mode Decomposition (EMD) algorithm is a non-linear non-stationary algorithm. Its time-frequency resolution adaptively changes with the signal, so it can have higher resolution in various situations, and medical denoising and other fields have been widely used. However, when the signal-to-noise ratio is low, the performance of the EMD method is degraded due to noise. In this paper, an adaptive filtering method is proposed. By estimating the noise power under different conditions, the denoising process is adaptively performed, and a better filtering effect is achieved compared to the conventional method.
