On wideband broadcast channels

Proceedings. 1998 IEEE International Symposium on Information Theory (Cat. No.98CH36252), 2002
We 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 ...

Broadcast channels in Estelle

IEEE Transactions on Computers, 1991
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).

BROADCAST CHANNEL TRANSMISSION CAPACITY

Vestnik komp'iuternykh i informatsionnykh tekhnologii, 2019
The most important studies of well-known Broadcast Communication Channels (BCC) models are associated with obtaining accurate information efficiency estimates(IE). Earlier, the coding problem was stated, the joint information measure (JI) of the proposed BCC model was introduced and investigated.

Precoder Design for MIMO Broadcast Channels

2005 Australian Communications Theory Workshop, 2005
This paper considers precoder designs in downlink MIMO broadcast channels (BC). A preceding scheme that is analog to the MMSE decision feedback equalizer in the uplink MIMO multiple access channels is first introduced. The proposed scheme can asymptotically achieve the sum-capacity of MIMO-BC at high SNRs. At medium SNRs, its achievable sum capacity is

Asymmetric Broadcast Channels

1981
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.

Parallel relay broadcast channels

2010 IEEE International Symposium on Information Theory, 2010
In this paper, we study the achievable rate regions of parallel relay broadcast channels. We present two system models, the parallel unshared-relay broadcast channel and the parallel shared-relay broadcast channel. In the first system, each relay node is peculiar to one of the users and does not assist any other user.

Degraded Broadcast Channels

1978
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 * .

Comments on broadcast channels

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.
