Abstract: In this paper, the use of a real-time perceptual speech quality metric
(RTPSQM) in power control of the Universal Mobile Telecommunication
System (UMTS) is investigated. It is shown that with this
approach the efficiency of the power control techniques in UMTS
is improved. In particular, the average Signal-to-Interference Ratio
(SIR) target can be reduced by the proposed RTPSQM-based power
control compared to the conventional algorithm while keeping the
perceptual quality in the desired range. This benefit can be large
for particular shadowing profiles.
