Open PhD position "VoIP Quality", Deutsche Telekom Labs, TU Berlin
The research group "Assessment of IP-based Applications" of Deutsche Telekom Laboratories, which is part of Berlin Institute of Technology (Technische Universität Berlin / TU Berlin) seeks candidates to fill, as soon as possible, an open PhD position in the field of VoIP-based Services and Quality Assessment (2 years initial funding, can be prolonged):
"Quality of VoIP"
Our goal is to carry out research in the area of services based on Voice over IP and the perceived quality it is related with. Here, aspects at signal-, network- and perception-level will be considered. The research will be conducted with the aim of developing quality prediction models and measurement approaches for VoIP service monitoring.
. Investigate the role of temporal aspects in the context of IP-based transmission, considering the relevant time-scales at packet-, speech, and perception-level.
. Investigate the impact of the transmitted signal form on the perceived speech quality.
. Investigate the quality related with new telephone services with extended bandwidth (wideband, 50-7000 Hz, superwideband, 50-14000 Hz).
. Research on models for speech quality prediction and tools for monitoring IP-based speech services.
. Research on how to best include end-user terminal equipment in quality estimates, using respective report protocols
The successful candidate holds a diploma or master's degree in Electrical Engineering, Computer Science, Communication Sciences, or a comparable field. For this position, genuine interest in and knowledge of telecommunications, the willingness to work in an international and interdisciplinary team, and the capability of independent work are a must. Solid knowledge of acoustics or speech technology, and interest in auditory perception, as well as knowledge of the English language are required, prior knowledge of auditory or speech perception and knowledge of MATLAB and C(++) are a definite plus.
Deutsche Telekom Laboratories (T-Labs) is a joint scientific research institute of Deutsche Telekom AG and Berlin Institute of Technology (TU Berlin). We carry out pioneering research into innovative information and telecommunication technologies, in particular addressing human perception and interaction, networking and security issues. The Laboratories are located on the campus of Berlin University of Technology, with the goal of promoting the interaction between science and business through physical proximity.
The Assessment of IP-based Applications Lab (www.aipa.tu-berlin.de) of Deutsche Telekom Laboratories (Prof. Dr.-Ing. Alexander Raake) is a newly founded research group, which carries out research on IP-based multimedia applications and user perception. The work will be conducted in exchange with other researchers working, for example, on parametric IPTV- and video-telephony quality models, multimedia transmission, audio-rendering and speech quality assessment. The work will be carried out in close collaboration with the monitoring department of Deutsche Telekom, with the aim of applying the developed algorithms and tools for monitoring real-life VoIP services.
