Abstract
Power control based on signal-to-interference ratio (SIR) has been proposed as a technique for managing cochannel interference due to frequency reuse in a time-division multiple access (TDMA) radio system. A previous study, assuming no adaptation to Rayleigh fading (i.e., slow power control), has indicated that a simple autonomous power control technique performs nearly as well as an ideal centralized SIR balancing/call removal policy. In this paper, we investigate the combined interference and fading adaptation effect of autonomous power control with a fast adjustment rate compared to the rate of Rayleigh fading in typical pedestrian users' radio environments. Tracking short-term fading is found to result in an additional improvement in SIR of 4 to 4.5 dB relative to the performance obtained with slow power control, thus providing a further increase in radio link quality.
