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.

Capacity bounds for identification via broadcast channels that are optimal for the determination broadcast channel

IEEE Transactions on Information Theory, 1990
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.

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
