School of Electrical Engineering and Computer Science at KTH

Project description

Wireless technology has evolved over five generations, but the need for higher efficiency and reliability is never-ending. The 6G research goal is to identify new groundbreaking methods that can enable tomorrow’s wireless applications. Specifically, the interest toward even higher frequencies beyond millimeter wave remains high for 6G and beyond. This particularly includes sub-terahertz (sub-THz, 100 GHz – 300 GHz) and terahertz (THz, 300 GHz – 3 THz) bands that theoretically enable both extremely high rate connectivity and extremely high-resolution sensing.

In this doctoral project, you will contribute to the theory formation for mobile sub-THz and THz wireless communication systems for 6G and beyond and establish yourself at the international forefront. Some possible research sub-areas are related to physically large antenna arrays, near-field THz communications, intelligent reflecting surfaces, joint terahertz communication and wireless sensing, and terahertz communications for satellite networks, but there are opportunities to adapt the research to your personal interests. The research will focus on the physical layer and media access control layer. Methods from probability theory, communication theory, electromagnetics, optimization and machine learning will play an important role.

The research is fully funded and will be carried out at the Division of Communication Systems under the supervision of Vitaly Petrov and Emil Björnson. The results will be published in top-level journals and prepare you for a research career in academia and industry.

Third-cycle subject:  Information and Communication Technology

Supervision: Professor Emil Björnsson

  • passed a second cycle degree (for example a master's degree), or
  • completed course requirements of at least 240 higher education credits, of which at least 60 second-cycle higher education credits, or
  • acquired, in some other way within or outside the country, substantially equivalent knowledge

In addition to the above, there is also a mandatory requirement for English equivalent to English B/6, read more here


In order to succeed as a doctoral student at KTH you need to be goal oriented and persevering in your work. During the selection process, candidates will be assessed upon their ability to:

  • independently pursue his or her work
  • collaborate with others,
  • have a professional approach, 
  • analyse and work with complex issues and
  • communicate effectively in English

After the qualification requirements, great emphasis will be placed on personal competency. 

Target degree: Doctoral degree

Information regarding admission and employment

Only those admitted to postgraduate education may be employed as a doctoral student. The total length of employment may not be longer than what corresponds to full-time doctoral education in four years ' time. An employed doctoral student can, to a limited extent (maximum 20%), perform certain tasks within their role, e.g. training and administration. A new position as a doctoral student is for a maximum of one year, and then the employment may be renewed for a maximum of two years at a time. In the case of studies that are to be completed with a licentiate degree, the total period of employment may not be longer than what corresponds to full-time doctoral education for two years.
