Abstract

A dual-adaptive linear prediction (DALP) method is presented to predict radio channel with abrupt change caused by appearance or disappearance of scattered components (SCs), based on the idea that the prediction error of classical adaptive linear prediction (CALP) method can also be predicted when the channel changes abruptly. The proposed predictor consists of a CALP and a linear predictor for error of CALP. It is just a simple combination of two linear predictors, but it is useful for the prediction of radio channel with abrupt change. As is verified through simulations on a simplified channel model, it can significantly speed the convergence process and maintain the accuracy of prediction at the cost of a little higher computational complexity compared with CALP.
