DOI: 10.1109/tvt.2018.2874819
Abstract: A massive multiple-input multiple-output (MIMO) requires a large number of antennas and the same amount of power amplifiers (PAs), one per antenna. As opposed to 4G base stations, which can afford highly linear PAs, next-generation… read more here.

DOI: 10.1109/tvt.2022.3203859
Abstract: We tackle the peak to average power ratio (PAPR) reduction of an orthogonal frequency division multiplexing (OFDM)-based massive multi-user (MU) multiple-input multiple-output (MIMO) downlink systems in this paper. Utilizing the redundant degree of freedom (DOF)… read more here.
