MISO Broadcast Channel under Unequal Link Coherence Times and Channel State Information [PDF]

Entropy, 2020
The broadcast channel may experience unequal link coherence times due to a number of factors including variation in node mobility or local scattering conditions.

Cooperative Relay Broadcast Channels [PDF]

2005 International Conference on Wireless Networks, Communications and Mobile Computing, 2005
The capacity regions are investigated for two relay broadcast channels (RBCs), where relay links are incorporated into standard two-user broadcast channels to support user cooperation.

Broadcast Channels with Cooperating Decoders [PDF]

IEEE Transactions on Information Theory, 2005
We consider the problem of communicating over the general discrete memoryless broadcast channel (BC) with partially cooperating receivers. In our setup, receivers are able to exchange messages over noiseless conference links of finite capacities, prior ...

Broadcast Channel Cooperative Gain: An Operational Interpretation of Partial Information Decomposition [PDF]

Entropy
Partial information decomposition has recently found applications in biological signal processing and machine learning. Despite its impacts, the decomposition was introduced through an informal and heuristic route, and its exact operational meaning is ...

A Novel Approach for Improving XML Querying over Wireless Broadcast Channels [PDF]

Sensors
The querying of large XML data over wireless broadcast channels can reduce bandwidth utilization, cause significant latency, and produce inefficient energy usage.

Unified Space–Time-Message Interference Alignment: An End-to-End Learning Approach [PDF]

Entropy
This paper investigates the performance of a multi-user multiple-input single-output (MU-MISO) broadcast channel under the practical constraints of imperfect, delayed, and quantized channel state information at the transmitter (CSIT).

Broadcast Channel Simulation

2023 IEEE International Symposium on Information Theory (ISIT), 2023
We study the problem of random-assisted simulation of discrete broadcast channel in one-shot and i.i.d. setups. We derive one-shot inner and outer bounds of the set of attainable message-size pairs for simulating W YZ|X within some total variation distance (TVD) tolerance of ϵ. The inner bounds are based on the bipartite convex split lemma. Whereas the

Identification over quantum broadcast channels [PDF]

Quantum Information Processing, 2022
AbstractIdentification over quantum broadcast channels is considered. As opposed to the information transmission task, the decoder only identifies whether a message of his choosing was sent or not. This relaxation allows for a double-exponential code size.

The Broadcast Approach in Communication Networks

Entropy, 2021
In this paper we review the theoretical and practical principles of the broadcast approach to communication over state-dependent channels and networks in which the transmitters have access to only the probabilistic description of the time-varying states ...
