Abstract

Performance of time-frequency distribution (TFD) based instantaneous frequency estimators for one-component, linear and quadratic FM signals is investigated under two models of multiplicative noise: Gaussian and impulsive. The periodogram (which is a specific time-frequency distribution (TFD)) of linear and non-linear FM signals has been considered. Two statistical models of multiplicative noise (Gaussian, impulsive) are handled. Simulation results show that impulsive noise has less impairment effect than Gaussian noise with the same power for instantaneous frequency estimation based on periodogram with multiplicative noise power less than 3 dB; however, the periodogram fails at multiplicative noise power more than 3 dB for both models of multiplicative noise (Gaussian, impulsive).
