Internet Telephony Over Wireless Links

Wolisz Berichter: Prof. Dr.-Ing. Steinmetz Berichter: Prof. Dr.-Ing. Sikora Tag der wissenschaftlichen Aussprache: 16. Dezember 2005 Berlin 2006 D83 c 2005-2006 by Christian Hoene Jahnstr. 22 72144 Dußlingen Germany [email protected] As a small child, you never spoke that clearly, no wonder that you want to improve the speech perceptibility. My mother, after hearing my thesis topic. Abstract This thesis presents algorithms to enhance the efficiency of packetized, interactive speech communication over wireless networks. The results achieved are the following: We present an improved approach to assess the quality of voice transmissions in IP-based communication networks. We combined the ITU E-Model, the ITU PESQ algorithm, and various codec and playout schedulers to analyse VoIP traces. Parts of this algorithm have been included in ITU standards. By using this assessment approach we derived design guidelines for application and data-link protocols. Also, we developed a quality model to parametrise adaptive VoIP applications. Later results received a best-paper award. If highly compressed packetized speech is transported over packet networks, losses of in- dividual packets impair the perceptual quality of the received stream differently, depending on the content and context of the lost packets. We introduce the idea of the Importance of Individual Packets, which is defined by the impact of VoIP packet loss on speech quality. -
