Abstract
A method of modeling channel parameters in Doppler environments estimates both the channel model and the coefficients simultaneously, thus not requiring additional packet overhead. This adaptive technique refines the channel coefficients as the estimate of the model accuracy improves with channel measurements. The underlying models are very accurate representations of Jakes models because they are computed off-line, thus the error prone approaches of trying to estimate one model from the observations are avoided.
