In order to estimate m-parameter of Nakagami-m multipath fading, different estimation models have been proposed and simulated, and their performances have already been compared. In this paper, we propose new method for estimation of m-parameter, which is not based on estimation from signal envelope samples, but on quotient of successive samples. For that purpose, analytical model which describes statistics of successive samples quotients has been developed. Two models have been treated, these are moment based method (MM) and maximum likelihood method (MLM). Numerical simulations will demonstrate performances of proposed methods and will compare them with some known methods in cases of presence and absence of shadow fading with arbitrary distribution.
