Covert Communications With Randomly Distributed Wardens in the Finite Blocklength Regime

Medicine-Engineering Interdisciplinary Research Based on Bibliometric Analysis: A Case Study on Medicine-Engineering Institutional Cooperation of Shanghai Jiao Tong University

“…Based on the received signal (4), Bob can decode the messages. The decoding error cannot be ignored in shortpacket communications, which is given by [7]…”

“…Since the decoding error probability ( 5) is affected by fading channels h ab and h wb , the average decoding error probability δ is adopted to evaluate the reliability performance. And the effective throughput of the system is given by [7]…”

“…In addition, [5], [6] investigated the throughput over quasi-static fading channels, revealing the fundamental difference in the design between the case of quasi-static fading channel and that of AWGN channel. More complex scenarios with multiple warders, multi-antenna sources and unmanned aerial vehicle aided networks were considered in [7]- [9].…”

Distributed secure transmission for covert communication under multi‐user network

“…(3) Lower extra complexity Compared with the scheme under the scenario with multiple wardens [20][21][22], the DSTCC scheme is more pragmatic. Lower extra complexity is achieved, which includes a little complexity of reception processing at destination.…”

“…Reference [21] proposed a UAV-aided covert communication scheme against several randomly distributed wardens. Reference [22] investigated covert communications in the presence of multiple randomly distributed wardens, where non-colluding and colluding detection strategies are considered in the derivation of the constraint. Accordingly, the transmission with covertness and security has also become the object of attention.…”
