AUDIO QUALITY MEASUREMENTS

TEMS Investigation supports AQM/PESQ and SQI measurements

PESQ (ITU P.862.1) is an algorithm designed to mimic human speech perception. A speech

sentence is played on the voice channel, and PESQ is computed by comparing the transmitted

sentence with an undistorted reference.

SQI (Speech Quality Index) is a proprietary algorithm which uses radio link parameters to

calculate the perceived speech quality on a radio channel.

TEMS Investigation supports mobile-to-mobile and mobile-to-fixed

AQM/PESQ measurements

Use SQI as complement to AQM/PESQ measurements


Flexible AQM/PESQ solution


SPEECH QUALITY INDEX (SQI)

A proprietary algorithm which uses radio link parameters to calculate the

perceived speech quality on a radio channel

DL measurements

Computing SQI for GSM/WCDMA requires Sony Ericsson phones.

SQI for CDMA can be enabled by any CDMA phone that is supported by TEMS Investigation

No additional HW is required

Input to SQI-MOS algorithm

Frame error rate

Bit error rate*

Speech codec used

SQI output is presented in dBQ* or MOS scale


Powerful speech quality estimation

*Valid for GSM and WCDMA


AQM/PESQ MEASUREMENTS

Mobile-to-mobile and mobile-to-fixed

AQM is more than PESQ

units, or a mix of both

Mobile-to-fixed and mobile-to-mobile

Note the difference between the two solutions, in areas like measurements,

dimensioning, troubleshooting, and workflow

PESQ UL and DL vs. PESQ DL

One radio link affecting each PESQ score vs. two radio links affecting each PESQ score

Impact of PSTN vs. impact of MRU location
