Abstract

The predictor coefficients of a mobile radio channel predictor have to be adapted to the changes in the radio environment. A direct adaptive predictor for the taps of a mobile radio channel is proposed. The coefficients of the predictor are assumed to change according to a filtered random walk model and are tracked using a Kalman filter. The filtered random walk is the simplest linear model that describes smooth changes of the coefficients and that includes integration. The proper choice of tuning parameters is discussed.
