Millimeter wave (mmWave) wideband channels in a multiple-input multiple-output (MIMO)
transmission are described by a sparse set of impulse responses in the angle-delay, or …

Channel estimation for hybrid Multiple Input Multiple Output (MIMO) systems at Millimeter-
Waves/sub-THz is a fundamental, despite challenging, prerequisite for an efficient design of …

Generalized multivariate analysis of variance (GMANOVA) and related reduced-rank
regression are general statistical models that comprise versions of regression, canonical …

A survey about linear channel estimation exploiting slowly varying channel properties is
given for receivers with multiple antenna elements. The slowly varying channel properties …

In this paper, we investigate the benefits of exploiting the a priori information about the
structure of the multipath channel on the performance of channel estimation for multiple …

Optimization of adaptive signal processing algorithms for wireless communications is based
on a model of the underlying propagation channel. In practice, this model is never known …

In this paper, a new method is proposed for direction-of-arrival (DOA) estimation of coherent
signals with improved sparse representation in unknown spatially correlated Gaussian …

This paper proposes techniques for Beam Alignment (BA) in millimeter wave (mm-wave)
Vehicle-to-Everything (V2X) communications with realistic modeling of the dynamic space …

In this paper, we develop and analyze the basic methodology for minimum-energy (ME)
band-limited prediction of sampled time-variant flat-fading channels. This predictor is based …

It is well known that classic direction-of-arrival (DOA) estimation techniques yield
unsatisfactory performance with limited snapshots in unknown nonuniform noise. In this …
