Millimeter wave communications channel estimation via Bayesian group sparse recovery

Raj Tejas Suryaprakash, Milutin Pajovic, Kyeong Jin Kim, Philip V. Orlik

ICASSP 2016accepted

We consider the problem of channel estimation for millimeter wave communications (mmWave). We formulate channel estimation as a structured sparse signal recovery problem, in which the signal structure is governed by a priori knowledge of the channel characteristics. We develop a Bayesian group spars…

Algorithms and performance analysis for estimation of low-rank matrices with Kronecker structured singular vectors

Raj Tejas Suryaprakash, Brian E. Moore, Raj Rao Nadakuditi

ICASSP 2015accepted

We consider the problem of estimating the singular vectors of low-rank signal matrices buried in noise in the setting where the singular vectors are assumed to be Kronecker products of unknown vectors. We propose four algorithms for estimating such singular vectors, analyze their performance and sho…
