Asymptotic Behavior of Error Exponents in the Wideband Regime

open access: yes, 2005
In this paper, we complement Verd\'{u}'s work on spectral efficiency in the wideband regime by investigating the fundamental tradeoff between rate and bandwidth when a constraint is imposed on the error exponent.

Non-parametric Estimation of Mutual Information with Application to Nonlinear Optical Fibers

open access: yes, 2018
This paper compares and evaluates a set of non-parametric mutual information estimators with the goal of providing a novel toolset to progress in the analysis of the capacity of the nonlinear optical channel, which is currently an open problem.

Tardos’s Fingerprinting Code over AWGN Channel [PDF]

open access: yes, 2010
Binary fingerprinting codes with a length of theoretically minimum order were proposed by Tardos, and the traceability has been estimated under the well-known marking assumption. In this paper, we estimate the traceability and the false-positive probability of the fingerprinting code over AWGN channel, and propose a new accusation algorithm to catch ...

Hybrid STA With FNN and CNN Models for Robust Channel Estimation in Turbulent FSO and Doppler‐Affected OFDM transmission for LEO Satellite Communication

open access: yesIET Communications, Volume 20, Issue 1, January/December 2026.
A hybrid framework of deep learning‐based channel estimation for robust communication in free space optical (FSO)‐based low earth orbit (LEO) satellite system using advanced modulation formats for orthogonal frequency division multiplexing (OFDM) transmission. Simulations demonstrate that STA‐ SRCNN and STA‐DNCNN excel in terrestrial FSO channels (NMSE

Quasi-Concavity for Gaussian Multicast Relay Channels

open access: yesEntropy, 2019
Standard upper and lower bounds on the capacity of relay channels are cut-set (CS), decode-forward (DF), and quantize-forward (QF) rates. For real additive white Gaussian noise (AWGN) multicast relay channels with one source node and one relay node ...

Lyapunov Exponent Testing for AWGN Generator System

open access: yesCommunications and Network, 2014
Additive White Gaussian Noise (AWGN) is common to every communication channel. It is statistically random radio noise characterized by a wide frequency range with regards to a signal in communication channels. In this paper, AWGN signal is generated through design an analogue circuit method, and then the multiple recursive method is also used to ...

A Novel Lightweight and High‐Performance Detection Framework for Signal Detection in Wideband Spectrogram

open access: yesElectronics Letters, Volume 62, Issue 1, January/December 2026.
With the proliferation of Internet of Things (IoT) devices, broadband signal detection in low‐signal‐to‐noise ratio (SNR) non‐cooperative environments presents significant challenges. This letter proposes two lightweight modules integrated into the YOLOv8 framework, which effectively reduces computational complexity while improving detection accuracy ...

The capacity region of broadcast channels with memory [PDF]

open access: yes, 1997
We derive the two-user capacity region of a broadcast channel with memory (ISI), assuming additive white Gaussian noise (AWGN) and an input power constraint.

Deep‐Learned Channel Estimation for MIMO‐OFDM System by Exploiting Frequency‐Space Correlation

open access: yesElectronics Letters, Volume 62, Issue 1, January/December 2026.
In massive MIMO–OFDM systems, accurate channel state information acquisition is vital for reliable transmission. Traditional methods fail to fully exploit sparse channel correlation, so an attentive residual autoencoder network is proposed. It uses an autoencoder with attention and residual connections to capture frequency–space correlation, and ...

Construction of Capacity-Achieving Lattice Codes: Polar Lattices

open access: yes, 2018
In this paper, we propose a new class of lattices constructed from polar codes, namely polar lattices, to achieve the capacity $\frac{1}{2}\log(1+\SNR)$ of the additive white Gaussian-noise (AWGN) channel. Our construction follows the multilevel approach
