Source of photons with correlated polarisations and correlated directions

Physics Letters A, 1992
Abstract We propose a source of photon pairs which uses two nonlinear crystals to produce pairs of photons (by parametric down conversion) that have correlated polarisations with the useful property that one photon of the pair always goes in one specific direction and the other photon always goes in another specific direction. This source can be used

Optimum beamformer in correlated source environments

The Journal of the Acoustical Society of America, 2006
A new method for overcoming signal cancellation problems due to correlated interferences which occur in a minimum variance distortionless response beamformer is proposed. Instead of decorrelating the correlated interferences, the coherently combining signal-to-interference plus noise ratio (CC-SINR) beamformer regards them as replicas of the desired ...

On zero-error coding of correlated sources

IEEE Transactions on Information Theory, 2003
The problem of separate zero-error coding of correlated sources is considered. Inner and outer single-letter bounds are established for the achievable rate region, and conditions for their coincidence are investigated. It is shown that successive encoding combined with time sharing is not always an optimal coding strategy. Conditions for its optimality

Feedback and Correlated Sources

2018
In this section, we shall see a special property of the AVC, which is that feedback increases the capacity. If noiseless feedback exists, a message is encoded to a function \(f^n=(f_1,\dots ,f_n)\) for \(f_1\in {\mathcal X}\) and \(f_t:{\mathcal Y}^{t-1}\rightarrow {\mathcal X}\), \(t=2,\dots ,n\), instead of a fixed codeword \(u\in {\mathcal X}^n ...

Communicating correlated sources over a MAC

2017 IEEE International Symposium on Information Theory (ISIT), 2017
The problem of characterizing sufficient conditions for communicating correlated sources over a MAC is considered. The technique of inducing source correlation onto channel inputs [1] is enhanced by the use of fixed B-L coding [2]. The performance of the proposed coding technique is characterized via single-letter expressions to derive a new set of ...

Infrasound source localization and correlation with seismic sources

The Journal of the Acoustical Society of America
Infrasound is widely used as a geophysical monitoring tool to detect and locate events of interest. Direct infrasound from atmospheric pressure disturbances can propagate long distances, allowing for reliable source localization. Infrasound can also be generated by underground sources which generally produce seismic waves in the solid Earth ...
