Abstract: Advanced algorithms have become available in recent years that can reliably measure the speech quality
as “perceived” by humans. The benefits of applying the perceptual quality measures obtained using these algorithms
in the Outer Loop Power Control (OLPC) of Third Generation Universal Mobile Telecommunication System
(3G UMTS) are studied in this letter. It is shown that 20% capacity improvement compared to the use of conventional
measures can be achieved while an adequate and uniform speech quality is maintained.
