Abstract

Abstract

A channel estimation scheme, using measured autocorrelation coefficients as weighting coefficients of the channel processor, and its error performance in equation are presented in this paper. Error performance of moving averaging channel estimation in equation is provided as well. Numerical and simulation results show that the proposed scheme can trace channel accurately and adaptively and outperforms moving averaging methods under not only fixed but also variant vehicle speeds.
