Reconstructing signals from noisy data with unknown signal and noise covariance
statistics information theory statistical mechanics
2011/8/17
Abstract: We derive a method to reconstruct Gaussian signals from linear measurements with Gaussian noise. This new algorithm is intended for applications in astrophysics and other sciences. The start...
Noisy channel coding via privacy amplification and information reconciliation
Noisy channel coding privacy amplification information reconciliation
2011/3/3
We show that optimal protocols for noisy channel coding of public or private information over either classical or quantum channels can be directly constructed from two more primitive information-theor...
On the Stability of Swarm Consensus Under Noisy Control
Adaptation and Self-Organizing Systems (nlin.AO) Multiagent Systems (cs.MA)
2010/11/10
Representation of a swarm of independent robotic agents under graph-theoretic constructs allows for more formal analysis of convergence properties. We consider the local and global convergence behavio...
Noise induced state transitions, intermittency and universality in the noisy Kuramoto-Sivashinksy equation
Noise induced state transitions intermittency universality noisy Kuramoto-Sivashinksy equation
2010/11/18
We analyze the effect of pure additive noise on the long-time dynamics of the noisy Kuramoto-
Sivashinsky (KS) equation in a regime close to the instability onset. We show that when the noise is high...

Reliability Function BSC with Noisy Feedback
2010/11/15
For information transmission a binary symmetric channel is used. There is also another noisy binary symmetric channel (feedback channel), and the transmitter observes without delay all the outputs of...
We consider the effect of Gaussian white noise on fast-slow dynamical systems with one fast and two slow variables, containing a folded-node singularity. In the absence of noise, these systems are kn...
Analysis of Nonlinear Noisy Integrate\&Fire Neuron Models: blow-up and steady states
Analysis Nonlinear Noisy Integrate\&Fire Neur Models blow-up steady states
2010/11/15
Nonlinear Noisy Leaky Integrate and Fire (NNLIF) models for neurons networks can be written as Fokker-Planck-Kolmogorov equations on the probability density of neurons, the main parameters in the mode...
We reformulate the information causality in a more general framework by adopting the results in signal propagation and computation in a noisy circuit. In our framework, the information causality lead...
Entanglement-Enhanced Classical Communication over a Noisy Classical Channel
Entanglement-Enhanced Classical Communication Noisy Classical Channel
2010/11/5
We present and experimentally demonstrate a communication protocol that employs shared entanglement to reduce errors when sending a bit over a particular noisy classical channel. Specifically, it is s...
Spectrophotometric Redshifts. A New Approach to the Reduction of Noisy Spectra and its Application to GRB090423
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
We have developed a new method, close in philosophy to the photometric redshift technique, which can be applied to spectral data of very low signal-to-noise ratio. Using it we intend to measure redshi...
We consider the problem of improving noisy quantum measurements by suitable preprocessing
strategies making many noisy detectors equivalent to a single ideal detector. For observables per-taining to ...

This paper examines the ability of greedy algorithms to estimate a block sparse parameter vector from noisy measurements.In particular, block sparse versions of the orthogonal
matching pursuit and th...

2010/12/16
Previous criteria for the feasibility of reconstructing phase information from intensity measurements, both in x-ray crystallography and more recently in coherent x-ray imaging, have been based on the...
