Abstract: This letter investigates a binary learning mechanism for statistical eavesdroppers’ channel state information (SECSI), in which the transmitter utilizes one-bit signal-to-noise-ratio feedback to constantly learn the channel correlation matrices of the eavesdropping links without any… read more here.

DOI: 10.1109/tsp.2022.3160004
Abstract: We design an efficient robust multi-group multicast beamforming scheme for massive multiple-input multiple-output (MIMO) systems. Assuming only estimates of the channel covariance matrices are available at the base station with a bounded error, we formulate… read more here.
