Fading Channel Prediction by Higher-Order Markov Model

Abstract

Optimal and energy-efficient use of the fading radio channel requires prediction of transmission channel gain. It is often necessary to predict this value several time frames in advance to compensate the delay in the feedback channel. In this paper, the fading predictor based on higher-order Finite-state Markov model is examined. In the proposed method, the impact of channel gain discretization and model's order on prediction accuracy for medium and fast Rayleigh fading channel is discussed.
