ANALYSIS OF SIGNALS BASED ON EMPIRICAL MODE DECOMPOSITION METHOD AND ITS APPLICATION ON SPEECH SIGNALS

Abstract

A method of signal decomposition on sinusoidal components (intrinsic mode functions), audio coding, a method of pitch tracking and a method of noise redaction are presented in this paper. The comparison of the performance of proposed method with other methods is analyzed.
