Outer Bounds on the Admissible Source Region for Broadcast Channels with Correlated Sources [PDF]
arXiv, 2015 Two outer bounds on the admissible source region for broadcast channels with correlated sources are presented: the first one is strictly tighter than the existing outer bound by Gohari and Anantharam while the second one provides a complete characterization of the admissible source region in the case where the two sources are conditionally independent ...

Polar coding for the wiretap broadcast channel
, 2023 In the next era of communications, where heterogeneous, asynchronous and ultra-low latency networks are drawn on the horizon, classical cryptography might be inadequate due to the excessive cost of maintaining a public-key infrastructure and the high computational capacity required in the devices.

Contention Resolution Without Collision Detection [PDF]
arXiv, 2020 This paper focuses on the contention resolution problem on a shared communication channel that does not support collision detection. A shared communication channel is a multiple access channel, which consists of a sequence of synchronized time slots. Players on the channel may attempt to broadcast a packet (message) in any time slot.

Capacity and Rate Regions of A Class of Broadcast Interference Channels [PDF]
arXiv, 2015 In this paper, a class of broadcast interference channels (BIC) is investigated, where one of the two broadcast receivers is subject to interference coming from a point-to-point transmission. For a general discrete memoryless broadcast interference channel (DM-BIC), an achievable scheme based on message splitting, superposition and binning is proposed ...

Capacity Theorems for Broadcast Channels with Two Channel State Components Known at the Receivers [PDF]
arXiv, 2015 We establish the capacity region of several classes of broadcast channels with random state in which the channel to each user is selected from two possible channel state components and the state is known only at the receivers. When the channel components are deterministic, we show that the capacity region is achieved via Marton coding.

Analysis of Intermodulation Distortion in OFDM Based Transmitter Using EER Technique [PDF]
Radioengineering, 2016 During the last two decades, new digital modulation systems have appeared in the audio broadcasting. Such broadcasting systems require new transmitters’ concepts to enable the transmission of digitally modulated signals. Moreover, the selected modulation

The Capacity Region of the Degraded Finite-State Broadcast Channel [PDF]
arXiv, 2008 We consider the discrete, time-varying broadcast channel with memory under the assumption that the channel states belong to a set of finite cardinality. We first define the physically degraded finite-state broadcast channel for which we derive the capacity region.
