APPLYING IIR PREDICTORS ON RAYLEIGH FADING SIGNAL

We present an efficient method of designing polynomial predictive IIR filters via feedback extension of FIR predictive filters. The advantag e of the W structures over their FIR counterparts is a more desirable frequency response obtained with considerably smaller memory and compu tational overhead. In this paper, we show that the IIR structure is ab le to predict complex-valued signals as well. This is demonstrated by the prediction of complex Rayleigh fading signal, where the W structur e is found to be clearly superior to the FIR structure in performance.
