A new receiver for additive white Gaussian noise channels

Integrated Computer-Aided Engineering, 2000
In this paper we study the performance of a wavelet-based receiver for the various digital communications modulation techniques, when the channel corrupts the transmitted signal by the addition of additive white gaussian noise (AWGN). This receiver is similar to the well-known optimum receiver in that it uses a correlator (matched filter) and a maximum

On the digital image additive white Gaussian noise estimation

2014 International Conference on Industrial Automation, Information and Communications Technology, 2014
Digital imaging is widely used in applications such as medical, biometrics, multimedia,…etc. In many cases, images are transmitted through Internet from one point to another. During image acquisition and transmission, factors such as moving objects, sensor quality, and channel interferences may result in additive noise.

Optimal tracking over an additive white Gaussian noise channel

2009 American Control Conference, 2009
This paper studies the optimal reference tracking problems of finite-dimensional, linear, time-invariant (LTI) systems with an additive white Gaussian noise (AWGN) channel between the controller and the plant. We consider two types of the reference signal: a random variable and a Brownian motion.

Codes for Covert Communication over Additive White Gaussian Noise Channels

2019 IEEE International Symposium on Information Theory (ISIT), 2019
We propose a coding scheme for covert communication over additive white Gaussian noise channels, which extends a previous construction for discrete memoryless channels. We first show how sparse signaling with On-Off keying fails to achieve the covert capacity but that a modification allowing the use of binary phase-shift keying for "on" symbols ...

On the capacity of additive white mixture Gaussian noise channels

Transactions on Emerging Telecommunications Technologies, 2019
AbstractThis paper provides an information‐theoretic study for the additive white impulsive noise channels by considering Gaussian mixture (GM) noise model, which includes Middleton class A andε‐mixture Gaussian models. First, three lower and two upper bounds are found for the differential entropy of complex multivariate GM distribution and these ...

Oblivious Transfer from the Additive White Gaussian Noise Channel

IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2010
We consider the use of the additive white Gaussian noise channel to achieve information theoretically secure oblivious transfer. A protocol for this primitive that ensures the correctness and privacy for players is presented together with the signal design.

A vector quantizer for additive white and colored Gaussian noise channels

Proceedings of IEEE International Symposium on Information Theory, 2002
Most of the work on joint source-channel coding deal with discrete channel models. We investigate the design of joint source-channel coding scheme for continuous-amplitude channels. More specifically, we propose a channel-optimized vector quantizer (COVQ) for additive white Gaussian noise (AWGN) and additive colored Gaussian noise (ACGN) channels with ...

Evolutionary Games for Hybrid Additive White Gaussian Noise Multiple Access Control

GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009
In this paper, we propose an evolutionary game-theoretic framework for hybrid additive white Gaussian noise multiple access channels. We consider a communication system consisting of multiple users and multiple receivers, where each user chooses a rate and splits it over the receivers.

On secret key agreement from the additive white Gaussian noise channel

2009 IEEE 20th International Symposium on Personal, Indoor and Mobile Radio Communications, 2009
It is known that noise on communication channels can be a powerful resource for certain cryptographic purposes, basically by utilizing the randomness to ensure the secrecy. In this paper, we study information theoretically secure key agreement through the use of the additive white Gaussian noise channel and public discussion.
