Further results on Nakagami-m parameter estimation

Accurate and efficient estimation of fading parameters are of considerable interest in the design of adaptive radios since they provide an indication of the communication link quality. We develop a few simple estimators for the Nakagami-m. parameter by approximating the transcendental equations that arise in the computation of maximum-likelihood and generalized moment-based estimators as linear or quadratic polynomials using a quasi-Newton optimization method. Statistical properties and the efficacy of the new estimators are validated via Monte Carlo simulations.
