Abstract

The method for estimating the parameters of multi-look Pareto distribution based on can not estimate the shape parameter less than 1. To overcome the drawback, it is generalized by, which widens the efficacious range for shape parameter to be estimated. The expression of parameter estimation is deduced so as to demonstrate that the proposed method is able to estimate the shape parameter less than 1 theoretically. The simulation results validate that the method of is able to estimate the shape parameter more efficaciously in the range of r=1.
