WMMSE design of digital filter banks with specified composite response
Amir Dembo,David Malah +1 more
TL;DR: The new weighted minimum mean square error (WMMSE) design method is interpreted from a statistical viewpoint as a maximization of the harmonic mean of the output signal-to-noise ratio (SNR) of the individual filters.
Journal ArticleDOI
Random walks among time increasing conductances: heat kernel estimates
TL;DR: In this paper, the authors established two-sided Gaussian transition density estimates and parabolic Harnack inequality for constant speed continuous time random walks evolving via time varying, uniformly elliptic conductances, provided the vertex conductances (i.e. reversing measures), increase in time.

Diffusions interacting through a random matrix: universality via stochastic Taylor expansion
Amir Dembo,Reza Gheissari +1 more
TL;DR: In this article, the authors show that the trajectories of averaged observables of a dynamical system with random coefficients are universal, i.e., only depend on the choice of the distribution through its first and second moments.
Journal ArticleDOI
The design of optimal uniform filter banks with specified composite response
Amir Dembo,David Malah +1 more
TL;DR: It is proved that for suitable design specifications and a wide class of optimization criteria, the optimal complex filter bank with specifications on its composite response is composed of frequency translated versions of a prototype filter.
