Asymmetric Broadcast Channels (ABCs) are of practical importance due to the physical differences between Broadcast Channels' (BCs') sub-channels in reality. In this paper, several classes of ABCs are studied and various inner and outer bounds on their capacity regions are given.

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.

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.

MIMO Broadcast Channels with Channel Estimation
2007 IEEE International Conference on Communications, 2007We consider a multi-user MIMO downlink where the transmitter has only estimates of the channel while the receivers have perfect channel information. The impact of channel estimation error on the sum rate is studied. It is shown that the sum rate saturates due to the inaccurate channel information.

Distributed broadcast channel access
Computer Networks (1976), 1979Abstract This paper presents a general approach to sharing a broadcast channel among multiple processors. There are two components to the problem of sharing a single resource: (1) How to specify the usage pattern of the resource; and (2) How to restrict access to the resource so that the specified usage pattern can be realized.

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 ...

Using notation consistent with the Estelle ISO 9074 International Standard, the syntax and formal semantics for a broadcast channel are presented. These semantics make precise the meaning of an intuitive concept and additionally are compatible with those of the current Estelle FDT (formal description technique).
