Sequences with Minimal Time-Frequency Uncertainty
Reza Parhizkar, Yann Barbotin, Martin Vetterli
A central problem in signal processing and communications is to design signals that are compact both in time and frequency. Heisenberg's uncertainty principle states that a given f…

Fast and Robust Parametric Estimation of Jointly Sparse Channels
Y. Barbotin, M. Vetterli
We consider the joint estimation of multipath channels obtained with a set of receiving antennas and uniformly probed in the frequency domain. This scenario fits most of the modern…

Estimation of Sparse MIMO Channels with Common Support
Yann Barbotin, Ali Hormati, Sundeep Rangan +1
We consider the problem of estimating sparse communication channels in the MIMO context. In small to medium bandwidth communications, as in the current standards for OFDM and CDMA…
