Communication Systems (KS)

The Division of Communication Systems conducts research and education in communications engineering, statistical signal processing and network science.

Photo credit: Karl ÖfverströmA principal focus of our research is the development of technology components for 6G wireless networks. Specific topics include the design and optimization of distributed and massive MIMO for high-capacity coverage and low-latency wireless access; methods to support energy-neutral (passive) devices and augmented, virtual and extended reality over wireless; design of wireless networks to support distributed AI and machine learning applications; and implementation of signal processing systems.

Security, robustness and energy-efficiency of communication links and networks are additional topics of importance.

Our work uses tools from statistical signal processing, information and communication theory, machine learning, complex networks and optimization.

Research projects

Illustration RadioWeaves - The emerging physical-layer infrastructure for 6G wireless communications

RadioWeaves – physical-layer infrastructure for 6G wireless communication

RadioWeaves is an emerging physical-layer wireless access infrastructure, in which a fabric of distributed radio devices and computing resources serve as a massive distributed antenna array.

Energy-Efficient Digital Signal Processing

Energy-Efficient Digital Signal Processing

Energy efficiency in signal processing hardware is vital for several reasons, in particular to reduce the environmental impact, to increase stand-by times, to make batteries smaller and lighter, and to simplify the cooling of circuits.

Distributed jamming of Massive MIMO

Physical layer security in massive MIMO

The inherent openness of the wireless channel makes wireless communication between two legitimate parties susceptible to attacks from a third party, the adversary. These attacks can be divided into two classes: eavesdropping and jamming.

Wireless Network Design for Decentralized Machine Learning

Wireless Network Design for Decentralized Machine Learning

This project aims at establishing a general framework for the joint design of information processing and wireless resource allocation to achieve communication efficiency and reliability in decentralized Machine Learning systems.

The participants at 2022 IEEE SPS - EURASIP Summer School

Focus on the super-fast 6G networks of the future

Hardly has 5G become a reality, when the question of what 6G will be like is asked? That was the starting point when the 2022 IEEE SPS - EURASIP Summer School was arranged at Linköping University.

Successful premiere for ISY's PhD Workshop

For the first time the Department of Electrical Engineering organized an all-day conference dedicated solely to the department's PhD-students. Afterwards the director of PhD studies, Mark Vesterbacka, was more than satisfied when he summed up the day

LiU researchers’ publications make waves in academia

Four researchers at Linköping University (LiU) have been included on a list of the world’s most cited academics. The list has been put together by the company Clarivate. Every year, Clarivate uses this list to celebrate influential researchers.

LiU students present cybersecurity report

Digitalisation is making us increasingly dependent on being online, which means that we are increasingly vulnerable to cyberattacks. LiU students Emmy Englund and Linnéa Tullin have written an in-depth report on cybersecurity in Sweden.
