On Continuous-Time Gaussian Channels [PDF]

open access: yesEntropy, 2019
A continuous-time white Gaussian channel can be formulated using a white Gaussian noise, and a conventional way for examining such a channel is the sampling approach based on the Shannon–Nyquist sampling theorem, where the original continuous-time ...

The Listsize Capacity of the Gaussian Channel with Decoder Assistance [PDF]

open access: yesEntropy, 2021
The listsize capacity is computed for the Gaussian channel with a helper that—cognizant of the channel-noise sequence but not of the transmitted message—provides the decoder with a rate-limited description of said sequence.

CRLBs for Pilot-Aided Channel Estimation in OFDM System under Gaussian and Non-Gaussian Mixed Noise [PDF]

open access: yesRadioengineering, 2012
The determination of Cramer-Rao lower bound (CRLB) as an optimality criterion for the problem of channel estimation in wireless communication is a very important issue. Several CRLBs on channel estimation have been derived for Gaussian noise.

Rate-compatible LDPC convolutional codes over non-gaussian noise channel [PDF]

open access: yesMATEC Web of Conferences, 2020
This paper is aimed to study the characteristics of the underwater acoustic channel with non-Gaussian noise channel. And Gaussian mixture model (GMM) is utilized to fit the background noise over the non-Gaussian noise channel.

Optimization of capacity in non-Gaussian noise models with and without fading channels for sustainable communication systems

open access: yesHeritage and Sustainable Development, 2023
The highest rate at which information may be reliably sent via a communication link is known as its capacity. In the case of non-Gaussian noise, the capacity of the channel depends on the specific characteristics of the noise, which can cause severe ...

Fidelity of Gaussian Channels [PDF]

open access: yesOpen Systems & Information Dynamics, 2004
A noisy Gaussian channel is defined as a channel in which an input field mode is subjected to random Gaussian displacements in phase space. We introduce the quantum fidelity of a Gaussian channel for pure and mixed input states, and we derive a universal scaling law of the fidelity for pure initial states.

Bosonic Gaussian channel and Gaussian witness entanglement criterion of continuous variables

open access: yesPhysical Review Research, 2023
We use quantum entanglement witnesses derived from Gaussian operators to study the separable criteria of continuous variable states. For bipartite system, we transform the validity of a Gaussian witness to a bosonic Gaussian channel problem.

Gaussian Multiuser Wiretap Channels in the Presence of a Jammer-Aided Eavesdropper

open access: yesEntropy, 2022
This paper considers secure communication in the presence of an eavesdropper and a malicious jammer. The jammer is assumed to be oblivious of the communication signals emitted by the legitimate transmitter(s) but can employ any jamming strategy subject ...

On the Classical Capacity of General Quantum Gaussian Measurement

open access: yesEntropy, 2021
In this paper, we consider the classical capacity problem for Gaussian measurement channels. We establish Gaussianity of the average state of the optimal ensemble in the general case and discuss the Hypothesis of Gaussian Maximizers concerning the ...
