Abstract: Study of channel behaviour for efficient spectral usage has been the key aspect in the design of third generation (3G) mobile communications systems. This paper deals with modelling of UHF signals acquired in a moving train corresponding to a distance of 180 km in northern India starting from New Delhi to Sharanpur, covering various environmental zones. A new sixth order adaptive polynomial model is proposed to further model the deviation of earlier adaptive three coefficient model. The standard deviations of the predictions made by the proposed model from the experimental data are within 2.1 dB throughout the region of experimentation in contrast to a maximum of 24 dB reported earlier.
