Post.doc.-position in Telecommunications at Department of Electronics and Telecommunications
within the area “Iterative Multiuser Detection, Decoding, and Channel Estimation” – Jnr. IME-011-2006.
One post-doctoral fellowship, funded by the Norwegian Research Council via the project Wireless LANSs with High Throughput in Interference-Limited Environments, is offered within the above-mentioned area. The appointment is made for up to 2 years.
Background:
Iterative structures for joint multiuser detection, decoding and channel estimation offer unique possibilities: In each iteration between the multiuser detector and the channel decoder reliability information on each transmitted bit is calculated. Some detected bits will be very unreliable, and some will be almost certain. These almost certain bits can then be used as “soft-pilots” to improve channel estimation. In that way the problem of having excessive pilot overhead can be overcome.
Goal:
When iteratively decoding multiple users, the problem of scheduling different parts of the graph-representation of the joint code-channel laws arises. Iterations eventually get stuck in practice. For the case of known channel state information, the convergence problem can be overcome by appropriate power assignment to the users. The goal of this research is to develop new methods that will give reliable convergence also for the case of imperfect channel estimation. This is a field that has not been sufficiently explored so far.
Applicants must have a doctorate degree from a recognized research institution with a thesis in the area of digital communications.
The position is remunerated according to salary code 1352, entry salary level 52-74 on the Norwegian State salary scale. This amounts to an annual gross salary of NOK 365.000.- – 548.000.- (equiv. to appr. US$ 54.400 – 81.600 at Febr.-2006), of which 2% is deducted for the Norwegian Public Service Pension Fund.
The successful applicant must agree to the conditions laid down for public employees.
Further information can be obtained from Professor Ralf R. Müller, Department of Electronics and Telecommunications, NTNU, at e-mail mueller@iet.ntnu.no
The national labour force must reflect the composition of the population to the greatest possible extent. It is therefore a major political objective to achieve a balance of age and gender and to recruit persons with an immigrant background. Immigrants are encouraged to apply for this post. NTNU wants to increase the proportion of women in its scientific posts. Women are encouraged to apply.
The application must contain information about education, examinations and previous experience. Certified copies of testimonies and documents must be attached.
Copies of publications and any other work which the applicant wishes to be taken into account should also be enclosed. Joint works will be considered. If it is difficult to specify the input of the applicant in a joint work, a short summary should be attached outlining the applicant's input.
Applications are to be sent to the Norwegian University of Science and Technology, Faculty of Information Technology, Mathematics and Electrical Engineering, Sem Sælands vei 9, N 7491 Trondheim, Norway. Applications should be marked IME-011-2006.
Closing date: 03.03.2006.
