Synchronous Concurrent Broadcasts for Intermittent Channels with Bounded Capacities [PDF]

open access: yesarXiv, 2020
In this work we extend the recently proposed synchronous broadcast algorithm amnesiac flooding to the case of intermittent communication channels. In amnesiac flooding a node forwards a received message in the subsequent round. There are several reasons that render an immediate forward of a message impossible: Higher priority traffic, overloaded ...

The capacity region of classes of product broadcast channels [PDF]

open access: yesarXiv, 2011
We establish a new outer bound for the capacity region of product broadcast channels. This outer bound matches Marton's inner bound for a variety of classes of product broadcast channels whose capacity regions were previously unknown. These classes include product of reversely semi-deterministic and product of reversely more-capable channels.

Relay Broadcast Channel with Confidential Messages [PDF]

open access: yesarXiv, 2013
We investigate the effects of an additional relay node on the secrecy of broadcast channels by considering the model of relay broadcast channels with confidential messages. We show that this additional relay node can increase the achievable secrecy rate region of the broadcast channels with confidential messages.

Performance Evaluation of the Emerging Media-Transport Technologies for the Next-Generation Digital Broadcasting Systems

open access: yesIEEE Access, 2017
Moving pictures experts group (MPEG) media transport (MMT) and MPEG-dynamic adaptive streaming over hypertext transfer protocol (MPEG-DASH) are emerging as the content-delivery technologies for the next-generation broadcasting systems, as they seamlessly

Degrees of Freedom Region of the Gaussian MIMO Broadcast Channel with Common and Private Messages [PDF]

open access: yesarXiv, 2011
We consider the Gaussian multiple-input multiple-output (MIMO) broadcast channel with common and private messages. We obtain the degrees of freedom (DoF) region of this channel. We first show that a parallel Gaussian broadcast channel with unmatched sub-channels can be constructed from any given Gaussian MIMO broadcast channel by using the generalized ...

An Efficient Design for the DVB-S2 Forward Link System Outer Layer Encoding Based on PCC Turbo Coding Across Fading Channel

open access: yesJournal of Engineering
The most significant challenges wireless broadcasting systems face are channel effects and Inter Symbol Interference (ISI). Many different kinds of channel coding are employed to get around these issues.
