An enhanced Markov chain based model for the narrowband LMS channel in built‐up areas

In this paper, a technique to derive the transition probabilities for a Markov chain model for the land mobile satellite (LMS) channel in built‐up areas is presented. This technique contributes to improving empirically derived parameters in that it can account for elevation and street orientation effects as well as building density. Physical‐statistical or ‘virtual city’ techniques are used to relate observed edification statistics to signal attenuation statistics. This methodology can also be applied to generating correlated time‐series for simultaneous links to a constellation of satellites from the same mobile terminal. The proposed approach also allows the generation of enhanced time‐series which take into account diffuse multipath and diffraction effects. Copyright © 2005 John Wiley & Sons, Ltd.
