Ph.D. student in Optimization and Modeling of Wireless Communication Systems

KTH in Stockholm is the largest and oldest technical university in Sweden. No less than one-third of Sweden’s technical research and engineering education capacity at university level is provided by KTH. Education and research spans from natural sciences to all branches of engineering and includes architecture, industrial management and urban planning. There are a total of just over 15,000 first and second level students and more than 1,600 doctoral students. KTH has almost 4,300 employees.

The School of Electrical Engineering conducts research and education in the fields of electrical engineering, systems engineering, information and communications theory, space and fusion plasma physics, and electrical power engineering. 300 people work in this creative and dynamic environment, out of which half are Ph.D. students, many from other countries. Our research projects are carried out in close collaboration with industry partners as well as with research colleagues from Sweden and other countries. The school is responsible for the educational program in electrical engineering and five masters programs which are in great demand and which have a close connection to our main fields.

Project description

The Signal Processing Lab at the School of Electrical Engineering conducts research in statistical signal processing and signal processing for communications. Research topics include transmission and coding techniques, receiver algorithms and detection, resource management and optimization, channel modelling, radio measurements, modelling and correction of RF components, instrumentation, positioning and navigation, and UWB ranging.

The Lab is now seeking one Ph.D-student in the area of wireless multi-user communication systems, exploiting multiple transmit and/or receive antennas, including both traditional MIMO scenarios as well as different cooperative scenarios where several nodes join forces when transmitting and receiving data. Optimization of the radio resources in such scenarios is highly non-trivial and should preferably be done using decentralized algorithms with a minimum of control signaling between the different nodes, at least over the air. Recent research has shown large potential benefits of letting several nodes cooperate, for example using so-called CoMP (Coordinated MultiPoint transmission or interference alignment). There are still many issues to investigate when turning these ideas into practically useful schemes, for example how to dynamically determine suitable clusters of nodes that should cooperate. Optimization of the radio parameters also requires suitable models of the system and of the interference situation.

Our Ph.D. program usually attracts a large number of highly qualified applicants and is aimed at only the most motivated students. It is a challenging but rewarding research education leading up to a degree that is internationally well respected. It provides a platform for a successful career in industrial R&D, academics, or for launching an innovative high-tech idea in a dynamic "start-up" business.

Our graduates are highly sought after upon graduation and can choose which part of the world they wish to work in. During your studies you will have the opportunity to regularly attend international conferences and workshops, visit research laboratories and academic institutions. This way you will build up a network of international contacts useful in your future career. Every student will also have the opportunity to spend an extended period (2-9 months) abroad at another top research lab.

The positions include approximately 80% research and 20% teaching responsibilities.
