Tracking and Compensating for Rayleigh Fading: Error Effects on Mobile Radio System Performance

Abstract

This work explores what benefits result from tracking and compensating for both lognormal shadowing and Rayleigh fading fluctuations in a mobile radio environment. The aim is in fact to demonstrate under what circumstances this choice can be taken advantage of by those power control policies which exclusively make use of local power level measurements in order to improve the performance, measured in terms of signal-to-cochannel interference ratio, of TDMA cellular radio systems. The corresponding analysis accounts for the errors due to the delay constraints that time division and transmission techniques such as interleaving inevitably force onto the control loops. The numerical results presented quantitatively outline the maximum benefits on system performance that a specific class of power control policies can achieve, revealing the remarkable influence of delay errors on the effectiveness of the control.
