Gaussian Broadcast Channel With Feedback

IEEE Transactions on Information Theory, 2008
For a Gaussian broadcast channel, it is known that: the capacity region in general is enlarged in the presence of feedback from all the receivers; and in the physically degraded case, feedback does not enlarge the capacity region. It is shown that the capacity region of a two-user Gaussian broadcast channel (GBC) is enlarged even when the feedback is ...

The capacity of a class of broadcast channels

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.

Control and Improvement of the Broadcast Channel

1977
The optimal control of the broadcast channel requires the knowledge of a non-measurable state variable, the number N of blocked terminals. After presenting some simulation results with N assumed to be known, we propose an adaptive control policy which we compare with the optimal control using a least squares estimator of N.

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.

Comments on Broadcast Channels

2009
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.
