Energy efficient transmit-receive spatial modulation for uplink-downlink large-scale MIMO systems

Abstract

Energy efficient spatial modulation-aided uplink and downlink designs for future millimeterwave (mmWave) large-scale multiple-input multiple-output (MIMO) systems are considered. Two novel uplink transceivers are proposed with the aim of considerably reducing the energy consumption at the user terminal, while achieving high spectral efficiency both in uplink and downlink transmissions. System performance is investigated using both stochastic and deterministic channels emulating real world urban scenarios.Peer Reviewe
