The problem of covert communication over Multiple-Input Multiple-Output
(MIMO) Additive White Gaussian Noise (AWGN) channels is investigated, in which
a transmitter attempts to reliably communicate with a legitimate receiver while
avoiding detection by a passive adversary. The covert capacity of the MIMO AWGN
is characterized under a variational distance covertness constraint when the
MIMO channel matrices are static and known. The characterization of the covert
capacity is also extended to a class of channels in which the legitimate
channel matrix is known but the adversary's channel matrix is only known up to
a rank and a spectral norm constraint.

变分距离约束下的隐蔽MIMO通信
研究了多输入多输出(MIMO)加性高斯白噪声(AWGN)通道上的秘密通信问题,其中,发送器尝试与合法接收器可靠地通信,同时避免被被动对手检测。当MIMO信道矩阵是静态的并且是已知的时,在变化距离隐蔽性约束下表征MIMO AWGN的隐蔽容量。隐性容量的表征也扩展到一类通道,在该类通道中已知合法通道矩阵,但仅在等级和频谱规范约束范围内才知道对手的通道矩阵。
