Study of Spectrum Analysis Based on EMD Adaptive Filter

The empirical mode decomposition (EMD) was recently proposed as a new time-frequency analysis tool for non-stationary and non-linear signals. Firstly, In this paper a new signal analysis method of adaptive filter-EMD-LMS is introduced. Secondly, spectrum analysis of simulated signals are used based on EMD-LMS. Compared with traditional spectrum analysis method, EMD-LMS is a better method for signal analysis and processing.
