Coupled estimators for equalization of fast-fading mobile channels
Linda M. Davis, Iain B. Collings, Robin J. Evans · IEEE Transactions on Communications · 1998
This letter presents a new method for identification of fast-fading mobile channels (for which combinations of vehicle speed and carrier frequency give rise to significant fading). Our new algorithm estimates both the channel statistics and the time-varying channel impulse response on-line. Simulation studies demonstrate the performance of the new estimator which couples an augmented Kalman filter with a recursive least squares algorithm.
