Time Reversal Communication in Multi-Path Fading Channels with Pinholes
Albert Fannjiang
The paper presents an analysis of the time reversal in multi-path Rayleigh-fading channels with inputs (transmitters) and outputs (receivers). The main issues addressed are…
Time Reversal of Broadband Signals in a Strongly Fluctuating MIMO Channel: Stability and Resolution
Albert Fannjiang
We analyze the time reversal of a multiple-input-multiple-output (MIMO) system in a space-frequency-selective multi-path fading channel described by the stochastic Schrödinger equa…
Quenching of Reaction by Cellular Flows
A. Fannjiang, A. Kiselev, L. Ryzhik
We consider a reaction-diffusion equation in a cellular flow. We prove that in the strong flow regime there are two possible scenario for the initial data that is compactly support…
Relaxation Time of Quantized Toral Maps
A. Fannjiang, S. Nonnenmacher, L. Wolowski
We introduce the notion of the relaxation time for noisy quantum maps on the 2d-dimensional torus - a generalization of previously studied dissipation time. We show that relaxation…
Self-Averaged Scaling Limits for Random Parabolic Waves
Albert C. Fannjiang
We consider 6 types of scaling limits for the Wigner-Moyal equation of the parabolic waves in random media, the limiting cases of which include the radiative transfer limit, the di…
Scaling Limits for Beam Wave Propagation in Atmospheric Turbulence
Albert Fannjiang, Knut Solna
We prove the convergence of the solutions of the parabolic wave equation to that of the Gaussian white-noise model widely used in the physical literature. The random medium is isot…
