In array processing, mutual coupling between sensors has an adverse effect on the
estimation of parameters (eg, DOA). While there are methods to counteract this through …

Sparse arrays such as nested and coprime arrays use a technique called spatial smoothing
in order to successfully perform MUSIC in the difference-coarray domain. In this paper it is …

Abstract The Cramér–Rao bound (CRB) offers a lower bound on the variances of unbiased
estimates of parameters, eg, directions of arrival (DOA) in array processing. While there exist …

This paper utilizes sparse array motion to increase the numbers of achievable both degrees
of freedom (DOFs) and consecutive lags in direction-of-arrival (DOA) estimation problems …

Coprime arrays, consisting of two uniform linear arrays whose inter-element separations are
coprime, can resolve O (MN) sources using only O (M+ N) sensors. However, holes in the …

Different from conventional phased-array radars, the frequency diverse array (FDA) radar
offers a range-dependent beampattern capability that is attractive in various applications …

Compressive sensing (CS) in acoustics has received significant attention in the last decade,
and thus motivates this special issue. CS emerged from the signal processing and applied …

A novel dilated nested array is presented to obtain an enhanced fully filled difference
coarray exploiting array motions. The proposed sparse array is suitable for the cases when …

In this paper, we investigate the interactions between a base station (BS) and a full-duplex
(FD) active eavesdropper in the uplink of multi-cell massive multiple-input multiple-output …

Linear [one-dimensional (1-D)] sparse arrays such as nested arrays and minimum
redundancy arrays have hole-free difference coarrays with O (N 2) virtual sensor elements …
