title = "Covert Downlink mmWave Communication for Massive MIMO LEO Satellite",
abstract = "We study covert downlink millimeter-wave (mmWave) communication for a low Earth orbit (LEO) satellite that uses massive multiple-input multiple-output (MIMO) hybrid beamforming and derive an explicit formula for the maximal covert transmission rate, known as the covert capacity. The covert communication is also known as communication with low probability of detection and it aims to prevent any illegal user to detect the occurrence of communication between legitimate users. Consistent with existing studies on covert communication, we use the total variance (TV) distance as the covertness measure. Furthermore, we propose a metric to measure the inherent sparsity of the mmWave massive MIMO channel and study its effect on the covert capacity. Our results provide insights and benchmarks for the design of practical covert communication strategies with LEO satellites, which is of interest in security-sensitive command and control systems.",
