    Xu, Z. J.; Lu, W. D.; Gong, Y.; Hua, J. Y.; Jin, W. B. (Společnost pro radioelektronické inženýrství, 2020-09)
    A covert communication system is proposed in this study, in which a~ non-zero mean Gaussian sequence is used as a~ random carrier and its mean is modulated by a~ covert binary bit. The aperiodic transmitted signal exhibits ...
