IEEE transactions on broadcasting, 2022
To protect military broadcasting against both hostile interference and eavesdropping, an artificial noise (AN) sheltered frequency hopping (FH) broadcasting (ANS-FHB) architecture is proposed in this paper, and the secrecy capacity is employed to measure

IEEE Transactions on Information Theory, 1972 We introduce the problem of a single source attempting to communicate information simultaneously to several receivers. The intent is to model the situation of a broadcaster with multiple receivers or a lecturer with many listeners. Thus several different channels with a common input alphabet are specified.

Comments on broadcast channels [PDF]
IEEE Transactions on Information Theory, 1998 Summary: The key ideas in the theory of broadcast channels are illustrated by discussing some of the progress toward finding the capacity region. The capacity region is still unknown.

Study on Air-to-Ground multipath channel and mobility influences in UAV based broadcasting
Information and Communication Technology Convergence, 2018In this paper, we present the study results on the possible multipath channel models for UAV(unmanned aerial vehicle) based broadcasting. In UAV based communications, the channel models consider only the path losses, the received signal strength and the ...

On wideband broadcast channels
Proceedings. 1998 IEEE International Symposium on Information Theory (Cat. No.98CH36252), 2002We study the capacity regions of various broadband degraded broadcast channels including the degraded Poisson broadcast channel and the degraded very-noisy broadcast channel. It is shown that in the absence of dark current the capacity region of the degraded Poisson broadcast channel is achievable with a simple time-sharing strategy, and an analogous ...

The capacity of a class of broadcast channels [PDF]
IEEE Transactions on Information Theory, 1979 The capacity region is established for those discrete memoryless broadcast channels p(y,z \mid x) for which I(X;Y) \geq I(X;Z) holds for all Input distributions. The capacity region for this class of channels resembles the capacity region for degraded message sets considered by Korner and Marton.

Broadcast-relay-broadcast channels
2010 Conference Record of the Forty Fourth Asilomar Conference on Signals, Systems and Computers, 2010In this paper, we study the achievable rate regions of broadcast-relay-broadcast channels. The source broadcasts information to the users. A number of parallel relays are used to assist users. Each relay receives information from the source and forwards information to users. The relays also broadcast the forwarded information to all users.
