ABSTRACT
In this paper we study the statistical performance of two moment-based estimators for the K parameter
of Rice fading distribution, as less complex alternatives to the maximum likelihood estimator. Our
asymptotic analysis reveals that both estimators are nearly asymptotically efficient, and that there is a
compromise between the computational simplicity and the statistical efficiency of these two
estimators. We also show, by Monte Carlo simulation, that the fading correlation among the envelope
samples deteriorates the performance of both estimators. However, the simpler estimator, which
employs the second and the fourth moments of the signal envelope, appears to be more suitable for
real-world applications.
