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

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.

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.

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.

Channel prediction and feedback in multiuser broadcast channels

2009 11th Canadian Workshop on Information Theory, 2009
Multiuser linear precoding requires channel state information (CSI) at the transmitter. In the absence of channel reciprocity between the uplink and downlink, a feedback mechanism must be designed to communicate CSI estimates from the mobile receivers to the transmitter.

Beaconing in MIMO Broadcast Channels

Proceedings. (ICASSP '05). IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005., 2006
There is a need to broadcast identical information to multiple users in a network. Examples include sending a beacon signal from an UAV to multiple sensors in a surveillance region and, in the context of ad hoc networks, multicasting. This paper studies the information theoretic aspects of multiple-input multiple-output (MIMO) beaconing where multiple ...

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 * .

On Fading Broadcast Channels with Channel Output Feedback

2022
The Broadcast Channel (BC) has been widely used as a downlink communication system model. One of particularly important BCs is the Fading Additive White Gaussian Noise Broadcast Channel (F-AWGN-BC), under various types of the Channel State Information (CSI) like perfect CSI at both the transmitter (CSIT) and receiver (CSIR), at the receiver only, or ...
