COUPLED ESTIMATORS FOR EQUALIZATION OF FAST-FADING MOBILE CHANNELS

This letter presents a new method for identification of fast-fading mo bile channels (for which combinations of vehicle speed and carrier fre quency give rise to significant fading). Our new algorithm estimates b oth the channel statistics and the time-varying channel impulse respon se on-line. Simulation studies demonstrate the performance of the new estimator which couples an augmented Kalman filter with a recursive le ast squares algorithm.
