Covert Communications in Multi-Channel Slotted ALOHA Systems
IEEE Transactions on Mobile Computing(2022)
Abstract
The fundamental limits of covert communication, where a message is sent from transmitter Alice to intended recipient Bob without detection by an attentive adversary warden Willie, has been considered extensively in recent years at the physical layer. The covert throughput depends critically on the warden's understanding of the characteristics of the radio environment and the type of receiver that ...
