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).

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.

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.

Comments on Broadcast Channels
2009The 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.

An inner bound to the capacity region for identification via a broadcast channel with feedback and a soft outer bound to the capacity region of a general broadcast channel without feedback are established, allowing randomized encoding in both cases.

Broadcast channels have been introduced by Cover in a paper published in 1972 [1] ; as an acknowledgement to the importance of this work he was granted the IEEE award in 1973. By now broadcast channels are firmly established as one of the most relevant channel networks for multi-terminal communication.

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.

Let A = {1,..., a}, B = {1,..., b}, and C = {1,..., c}. Let w1(· | ·) be the c.p.f. of a d.m.c. A → B, and w2(· | ·) the c.p.f. of a d.m.c. B → C. Write A n * for the Cartesian product of n A’s, with similar definitions for B n * , C n * , and, later, for D n * .

Synchronous atomic broadcast for redundant broadcast channels
Real-Time Systems, 1990We propose a synchronous atomic broadcast protocol for distributed real-time systems based on redundant broadcast channels. The protocol can tolerate a finite number f of concurrent processor crash failures, channel adapter performance failures and channel omission failures. Its message cost is optimal: when no failures occur only f+1 messages are sent
