Designing and characterizing MATE, the Chalmers mm-wave MIMO testbed
Paper i proceeding, 2018

In this paper, we report on the design and characterization of MATE, the mm-wave testbed at the Chalmers University of Technology. We elaborate around design choices of various parts of the testbed, baseband hardware, required software and RF frontend. We also perform a thorough characterization of the testbed, in terms of I/Q imbalance, stability, frequency offset, DC offsets, and ADC/DAC clock rate offset. The study shows that the utilized design techniques for baseband and RF frontend hardware are feasible, and also that many hardware imperfections are possible to accurately characterize, for subsequent calibration and digital compensation.
