Abstract:
The analysis of long signals is relevant in many fields, as biomedical signal analysis. In this paper, a revision of the Empirical Mode Decomposition (EMD), from the application point of view, is done. The increase in number of Intrinsic Mode Functions (IMF) and computational time in long signals are the main problems that have been faced in this work. A solution based on a sliding window is proposed. An adaptive process is used to calculate the size of the sliding Windows. As a result, the effectiveness of the proposed algorithm increases with the length of the signal. Two examples are introduced to illustrate both problems mentioned above.
