Channel capacities for list codes [PDF]

open access: greenJournal of Applied Probability, 1973
In the present paper we demonstrate that the concept of a list code is from a mathematical point of view a more canonical notion than the classical code concept (list size one) in that it allows a unified treatment of various coding problems. In particular we determine for small list sizes the capacities of arbitrarily varying channels.

Polar coding for fading channels [PDF]

open access: yes2013 IEEE Information Theory Workshop (ITW), 2013
A polar coding scheme for fading channels is proposed in this paper. More specifically, the focus is Gaussian fading channel with a BPSK modulation technique, where the equivalent channel could be modeled as a binary symmetric channel with varying cross-over probabilities.

LDGM Codes for Channel Coding and Joint Source-Channel Coding of Correlated Sources

open access: yesEURASIP Journal on Advances in Signal Processing, 2005
We propose a coding scheme based on the use of systematic linear codes with low-density generator matrix (LDGM codes) for channel coding and joint source-channel coding of multiterminal correlated binary sources. In both cases, the structures of the LDGM

Channel Coding at Low Capacity [PDF]

open access: yes2019 IEEE Information Theory Workshop (ITW), 2019
Low-capacity scenarios have become increasingly important in the technology of the Internet of Things (IoT) and the next generation of wireless networks. Such scenarios require efficient and reliable transmission over channels with an extremely small capacity.

Codes for the Z-Channel

open access: yesIEEE Transactions on Information Theory, 2023
This paper is a collection of results on combinatorial properties of codes for the Z-channel. A Z-channel with error fraction $τ$ takes as input a length-$n$ binary codeword and injects in an adversarial manner up to $nτ$ asymmetric errors, i.e., errors that only zero out bits but do not flip $0$'s to $1$'s.

Adaptive Combined Channel-Network Coding for Cooperative Relay Aided Cognitive Radio Networks

open access: yesInformation, 2021
Cognitive radio (CR) is one of the emerging technologies for 4G/5G applications. Cooperative relay communications and network coding are some techniques that helped in enhancing the CR applications.

Coding in Diffusion-Based Molecular Nanonetworks: A Comprehensive Survey

open access: yesIEEE Access, 2023
Diffusion-based molecular nanonetworks exploit the diffusion of molecules, e.g., in free space or in blood vessels, for the purpose of communication. This article comprehensively surveys coding approaches for communication in diffusion-based molecular ...

Channel coding: The road to channel capacity [PDF]

open access: yesProceedings of the IEEE, 2007
Starting from Shannon's celebrated 1948 channel coding theorem, we trace the evolution of channel coding from Hamming codes to capacity-approaching codes. We focus on the contributions that have led to the most significant improvements in performance vs.

Polar Codes for Broadcast Channels [PDF]

open access: yesIEEE Transactions on Information Theory, 2013
Polar codes are introduced for discrete memoryless broadcast channels. For $m$-user deterministic broadcast channels, polarization is applied to map uniformly random message bits from $m$ independent messages to one codeword while satisfying broadcast constraints.
