Code design for MIMO broadcast channels [PDF]

IEEE Transactions on Communications, 2006
Recent information-theoretic results show the optimality of dirty-paper coding (DPC) in achieving the full capacity region of the Gaussian multiple-input multiple-output (MIMO) broadcast channel (BC). This paper presents a DPC based code design for BCs.

Performance evaluation of MIMO broadcast systems for advanced digital terrestrial TV

EURASIP Journal on Wireless Communications and Networking, 2021
The transmission performance of spatial multiplexing cross-polarized MIMO is studied to determine how to increase the capacity of digital terrestrial broadcasting and make it more robust.

Universal superposition codes: capacity regions of compound quantum broadcast channel with confidential messages [PDF]

, 2019
We derive universal codes for transmission of broadcast and confidential messages over classical-quantum-quantum and fully quantum channels. These codes are robust to channel uncertainties considered in the compound model. To construct these codes we generalize random codes for transmission of public messages, to derive a universal superposition coding

Broadcast Channels With Privacy Leakage Constraints [PDF]

IEEE Transactions on Information Theory, 2017
The broadcast channel (BC) with one common and two private messages with leakage constraints is studied, where leakage rate refers to the normalized mutual information between a message and a channel symbol string. Each private message is destined for a different user and the leakage rate to the other receiver must satisfy a constraint.

Deep Kalman Neuro Fuzzy-Based Adaptive Broadcasting Scheme for Vehicular Ad Hoc Network: A Context-Aware Approach

IEEE Access, 2020
Vehicular Ad Hoc Networks (VANETs) are among the main enablers for future Intelligent Transportation Systems (ITSs) as they facilitate information sharing, which improves road safety, traffic efficiency, and provides passengers' comfort.

Secure information broadcasting analysis in an indoor VLC system with imperfect CSI

IET Communications, 2021
In this paper, the physical layer security of an indoor visible light communication system, that consists of two transmission light‐emitting diodes to broadcast the information towards the legitimate user, is investigated. Further, a secure LED selection

Quantum broadcast communication [PDF]

Chin. Phys., 2007, 16 (7): 1868-1877, 2006
Broadcast encryption allows the sender to securely distribute his/her secret to a dynamically changing group of users over a broadcast channel. In this paper, we just consider a simple broadcast communication task in quantum scenario, which the central party broadcasts his secret to multi-receiver via quantum channel. We present three quantum broadcast

The State-Dependent Semideterministic Broadcast Channel [PDF]

IEEE Transactions on Information Theory, 2012
We derive the capacity region of the state-dependent semideterministic broadcast channel with noncausal state-information at the transmitter. One of the two outputs of this channel is a deterministic function of the channel input and the channel state, and the state is assumed to be known noncausally to the transmitter but not to the receivers. We show

Reliable Broadcast despite Mobile Byzantine Faults [PDF]

arXiv, 2023
We investigate the solvability of the Byzantine Reliable Broadcast and Byzantine Broadcast Channel problems in distributed systems affected by Mobile Byzantine Faults. We show that both problems are not solvable even in one of the most constrained system models for mobile Byzantine faults defined so far.
