Abstract
A system and method automates the process of objectively measuring the subjective quality of packetized telecommunication signals as a function of network quality-of-service (QoS) parameters, implementation choices, and other related parameters. Computer-based simulation may be used in conjunction with objective quality measurement algorithms and pre-recorded reference or test signals. A system (300) employing this simulation method does not require the use of human subjects in subjective quality evaluation. The system and method are applicable to various types of telecommunication signals such as, for example, voice, video, audio, and multimedia.
