DOI: 10.1109/lwc.2020.3001003
Abstract: Spatial modulation (SM) maps information to both spatial dimensions (active antenna indices) and conventional 2D ${M}$ -ary symbols. The existing SM schemes use fixed number of active antennas in each transmit vector as varying them… read more here.

DOI: 10.1109/tmtt.2020.3032900
Abstract: A novel over-the-air (OTA) beamforming calibration procedure is proposed, which can be applied to different types of multiple-input multiple-output (MIMO) transmitting antennas. The method consists of using two tones on each antenna element, the main… read more here.
