Erik G. Larsson (erik.g.larsson@liu.se) received his Ph.D.
degree from Uppsala University, Sweden, in 2002. He is a professor at Linköping University, Sweden. His main professional
interests are within signal processing, communication theory,
applied information theory, wireless systems, and 5G. He was
the chair of the IEEE Signal Processing Society Signal
Processing for Communications and Networking technical
committee in 2015 and 2016, chair of the steering committee
of IEEE Wireless Communications Letters in 2014 and 2015,
and he organized the Asilomar Conference on Signals,
Systems, and Computers (general chair 2015, technical chair
2012). He received the IEEE Signal Processing Magazine Best
Column Award twice, in 2012 and 2014, and the IEEE
ComSoc Stephen O. Rice Prize in Communications Theory in
2015. He is a Fellow of the IEEE.
