PhD Scholarship Position in Digital Radio-over-fibre for Flexible Mm-wave Distributed Mimo Systems

Chalmers University of Technology is pleased to invite applicants to apply for a new opening PhD position in wireless communication. This position is available for 3 years. Applications should be sent before September 01, 2019.

The Department of Microtechnology and Nanoscience focuses on research, innovation and education within the fields of future electronics, photonics, bio- and nanosystems. A close collaboration with Swedish and international partners within academia, industry and society enables scientific excellence and creates an innovative environment. In addition to the 200 researchers and PhD students, MC2 houses a cleanroom for micro- and nanofabrication with the latest equipment.

Information about the research

The European Innovative Training Network 'MyWave' on Efficient Millimetre – Wave Communications for beyond – 5G offers 15 prestigious, fully funded PhD student positions in the area of millimetre-wave antennas, integrated circuits and signal processing, starting in the autumn of 2019. The MyWave consortium consists of 8 leading European R&D laboratories from universities, industries, and technology institutes in the domain of wireless infrastructure, which are located in The Netherlands, Sweden, Belgium and Germany.

Our society is on the brink of a new age with the development of new visionary concepts such as internet of things, smart cities, autonomous driving and smart industries. This stimulates the use of the mm-wave frequencies up to 100 GHz to support much higher data rates and to increase the capacity of mobile wireless communication systems to enable future beyond-5G infrastructure. This requires new system concepts such as Distributed Massive Multiple-Input-Multiple-Output (DM-MIMO) in which instead of a single base-station, the cell is covered by multiple remote antenna stations, all connected to a central unit. To overcome existing limitations, such as poor energy efficiency and poor signal quality, MyWave will focus on an innovative antenna system concept utilizing both silicon and III-V semiconductor technologies, advanced signal processing concepts and radio-over-fibre interconnect between a central unit and the remote antenna stations.

MyWave establishes a unique and well-structured training network with leading R&D labs from European industries, universities and technology institutes in the domain of wireless infrastructure and a proven track-record in joint collaborations. The 15 Early Stage Researchers (ESRs) will form a research team that is embedded in leading industrial and academic R&D labs. This will bridge the gap between the various disciplines by uniting their research efforts to solve the challenges.

This highly innovative training will provide the PhD students with a comprehensive set of theoretical and practical skills relevant for innovation and long-term employability in the rapidly growing sector of beyond-5G applications. Examples of specialized and unique cources/workshops that will be offered to the 15 ESRs are ‘Mm-wave antenna technologies ‘, ‘Distributed Massive MIMO systems’, ‘mm-wave measurement techniques’, ‘IC, packaging and PCB technologies ‘, ‘Multi-physics design of integrated antennas’, ‘Advanced mm-wave IC design’, and ‘Massive array signal processing’.

Each PhD student will be enrolled in a fully financed doctoral programme at the host University and is jointly supervised by supervisors from the academic and industry sector. As part of the PhD studies, each student will do a secondment (i.e. training) of 18 months abroad at one of the industrial partners.

Major responsibilities

This PhD student position is founded on the continuous improvement of semiconductors (Moores law), which has driven the development of ultra high-speed digital signal processing, optical interconnect technologies, and software defined radio architectures. You will investigate and push the fundamental component and communication limits of all-digital radio-over-fibre as a new means of realizing flexible mm-wave distributed massive MIMO systems. Based on this, our goal will be to build a test-bed that will give us unique possibilities to understand and experimentally demonstrate the required levels of communication, including RF-synchronisation, beamforming etc between distributed radio units in future wireless systems. The project is cross-disciplinary and will include the design and integration of key electrical- and optical hardware components and signal processing algorithms with the goal of maximizing communication system performance.

The position is hosted by the Microwave Electronics Laboratory at Chalmers, but it also involves a close collaboration with communication system researchers at Chalmers, and the optical communication team at Ericsson Research in Pisa/Italy where you will spend your industrial secondment as an integral part of your Chalmers PhD studies. You will thereby have access to state-of-the art microwave and photonics components, world-class measurement infrastructure, and advanced signal processing expertise as needed to carry out this exciting and challenging research project.

Your major responsibilities are to pursue your own doctoral studies. You are expected to develop your own scientific concepts and communicate the results of your research verbally and in writing, both in Swedish and in English. The position generally also includes teaching on Chalmers’ undergraduate level or performing other duties corresponding to 20 per cent of working hours.

Full-time temporary employment.The position is limited to a maximum of five years.


Applicants should have, or expect to soon receive, a Master of Science degree or equivalent in a relevant electrical engineering or applied physics discipline. In addition to the formal qualifications, selection is also based on the performance of the candidates in other works (e.g. thesis and advanced level courses), as well as through interviews and assignments. Besides good subject knowledge, emphasis will be on creative thinking, motivation, ability to cooperate, initiative to work independently and personal suitability for research training. Further, experience from RF circuit design, high frequency optical and microwave measurements, FPGA programming and/or advanced signal processing are all important merits. According to EU regulations in this program, a candidate student who has stayed in Sweden for more than 12 months in the last 3 years cannot apply to the PhD positions at Chalmers.

The position requires sound verbal and written communication skills in Swedish and English. If Swedish is not your native language, you should be able to teach in Swedish after two years. Chalmers offers Swedish courses.

Chalmers offers a cultivating and inspiring working environment in the dynamic city ofGothenburg.
