Performance analysis of AM-FM estimators

Abstract

We address the problem of decomposing a bandpass signal into amplitude and frequency modulated components (AM and FM respectively). Several estimators have been proposed in literature, each of which works under specific assumptions. In this paper, we perform a comparative study of some popular techniques by studying their performance with changes in the modulation parameters and the tradeoffs involved. We also study their performance in the presence of bandpass white Gaussian noise.
