Abstract: This paper evaluates the potential capacity improvements
in mobile radio systems due to perceptual-based power
control. It builds on our previous work on the application of a
Real-time Perceptual Speech Quality Metric (RTPSQM) in power
control. Encouraged by the performance improvements offered
with perceptual-based power control, this paper investigates on
how gains in average transmitter power and SIR target translate
to gains in the actual capacity in the Global System for Mobile
communication (GSM) and the Universal Mobile Telecommunication
System (UMTS). In particular, capacity improvements in
terms of number of users per cell between 25% to 91% are
obtained for perceptual-based power control in GSM. As for
UMTS, the results show an increase in Erlang capacity per cell
by at least 10%.
