The Comunications Engineering Division work with research and education in the area of communications, with foci on both the properties of transmission channels and on how to efficiently transmit information over these channels. A dominating part of the activities deals with different forms of wireless communications.

Some highlights:

• Together with Bell Labs and Linköping University, we are among the pioneers of massive MIMO research. For example, 4 of 7 authors of the classic paper "Scaling Up MIMO: Opportunities and Challenges with Very Large Arrays" published in the IEEE Signal Processing Magazine in 2012 are from our division; likewise 2 of 4 authors of another classic paper "Massive MIMO for next generation wireless systems" published in the IEEE Communications Magazine in 2014 are our division members. The division has also developed the first real-time massive MIMO testbed (LUMaMI) together with the Integrated Electronic Systems (IES) Division, with the support of hardware from National Instruments.

• We have contributed to a clearer understanding of the limitations of applying the orbital angular momentum (OAM) concept in wireless communications through the paper "Is orbital angular momentum (OAM) based radio communication an unexploited area?" published in IEEE Transactions on Antennas and Propagation in 2012.

• Major contributions have been made on Faster-than-Nyquist (FTN) signaling, allowing 30%–100% more data to be packed into the same bandwidth at the same energy per bit and error rate compared to traditional methods. A key paper in this area "Faster-Than-Nyquist Signaling" was published in the Proceedings of the IEEE in 2013.
