PESQ® Measurement for GSM with R&S®CMUgo

Recent mobile test methods could not evaluate the quality of data reduced speech signals with different coded and decoded signals. The Perceptual Evaluation of Speech Quality (PESQ) provides the solution for this measuring problem. GSM PESQ is an add-on tool for CMUgo for automatic measurement of the PESQ for GSM mobile phones according to recommendation ITU-T P.862.1 featuring selectable fading profiles, frequency hopping sequences and variable Additional White Gaussian Noise (AWGN).
