Abstract
The estimation of fading channel parameters is one key technique in wireless channel transmission system. This paper establishes an model based on Nakagami - m distribution in noise condition, and presents a Nakagami m parameter estimation based on higher order moments. This method utilizes such characteristic of higher order moments as detection Gaussian distribution feature to identify the property of fading channel. The theoretical analysis and experimental results prove the feasibility and effectiveness of the new method. The computational complexity for moment - based estimation is analyzed, and it was proved mathematically that its computational complexity is lower than maximum -likelihood estimator.关键词
