We consider the problem of optimal allocation of resources (power and bandwidth) between training and data for transmission over a Gauss Markov fading channel. Inaccurate channel state information ((CSI) is available at the receiver through periodic training. The transmitter is assumed to have knowledge of the channel Doppler spread. We compute the ergodic cutoff rate Ro for the temporally-correlated Rayleigh flat fading channels with imperfect channel state information (CSI) available at the receiver. We study MMSE estimators that predict the current channel state based on: all past pilot observations, only the most recent pilot observation, and the most recent and next in the future pilot observations.Army Research Lab Adelphi is the author of 'Analysis of Optimal Training for Correlated Fading Channels Using Cutoff Rate', published 2004 under ISBN 9781423516477 and ISBN 1423516478.
