Abstract

Aiming at the problem of high complexity and low practicability caused by the Bessel functions in the traditional first moment and second-order moment estimation algorithm, this paper proposed an improved moment estimation method based on the order selection of Bessel function. Firstly, this algorithm calculated the moment estimation value corresponding to different K by using original estimation formula, then calculated moment estimation value with Bessel function of different orders, further solved the corresponding K value and its estimation accuracy, finally, determined the order of Bessel function acquired and improved the estimation method. Experimental results show that the improved method obtains good performance in time consuming, especially for small K.
