Massive MIMO system aspects from a terminal perspective, 2015-01-01 - 2018-12-31
Massive MIMO (MM) technology is emerging as one of the major candidates for increasing efficiency of future wireless communications - both spectral and energy efficiencies. Recent predictions show that energy efficiency can be increased by several orders of magnitude and spectral efficiency by at least one order of magnitude, under reasonable assumptions on system configurations. Predictions like these have opened up a frenetic research activity in the field. Despite great efforts spent on investigating how efficient MM systems should be designed, the terminal perspective is almost entirely neglected. One reason for this is that most of the new concepts relate directly to the base station and only indirectly to the terminal devices. The terminal designs will, however, to a large extent influence how the MM systems of the future perform. Terminal design considerations will influence the entire systems, all the way from how well different MM transmission techniques perform under real conditions to how transmission protocols are designed. This project investigates influence of terminal devices on MM system performance, and how they should be designed to optimize system efficiency. The investigation spans the entire gamut from designing terminal prototypes to developing design methodologies. This is done by combining practical measurements and experimental studies in a MM testbed with more theoretical simulations and system optimizations.

DARE -- Digitally-Assisted Radio Evolution, 2011-03-01 - 2016-03-31
Digitally-Assisted Radio Evolution – DARE targets 4G/5G communications, implementing the key blocks of a radio transceiver in a commercial nm CMOS process. The full power of digital signal processing is deployed to control and adapt the performance of the analog/RF blocks, improving the trade-off between performance and power consumption.

MAMMOET, MAssive MiMO for Efficient Transmission, 2014-01-01 - 2016-12-31
Massive MIMO (MaMi) use several hundreds of base station antennas that operate phase-coherently together, simultaneously serving many tens of low-complexity single-antenna terminals in the same time-frequency resource. MAMMOET will demonstrate that MaMi can increase both data rates and the overall spectral efficiency by up to ten times, while decreasing the transmitted radiofrequency (RF) power by many orders of magnitude. The Massive MIMO Testbed LuMaMi is up and running in EIT labs.
