Coprime array offers a larger array aperture than uniform linear array with the same number
of physical sensors, and has a better spatial resolution with increased degrees of freedom …

A coprime array has a larger array aperture as well as increased degrees‐of‐freedom
(DOFs), compared with a uniform linear array with the same number of physical sensors …

It is known that there exist two kinds of methods for direction-of-arrival (DOA) estimation in
the literature: the subspace-based method and the sparsity-based method. However …

In this paper, we propose a generalized co-prime multiple-input multiple-output (MIMO)
configuration for direction of arrival estimation. Compared with the conventional coprime …

A coprime array is capable of achieving more degrees-of-freedom for direction-of-arrival
(DOA) estimation than a uniform linear array when utilizing the same number of sensors …

With the adoption of arbitrary and increasingly wideband signals, the design of modern
radar systems continues to be limited by analog-to-digital converter technology and data …

Narrowband Internet of Things (NB-IoT) is one of the most promising technologies for low-
power, wide-area, and low-traffic applications. In NB-IoT, random access is implemented in …

As a new emerging technology for wireless communications, massive multiple-input multiple-
output (MIMO) faces a significant challenge to deploy a separate receiver chain of front-end …

Unknown mutual coupling effect can degrade the performance of a direction of arrival
estimation method. In this letter, a new method is proposed for uniform linear arrays (ULAs) …

In this paper, we propose a novel coprime array adaptive beamforming algorithm based on
virtual array spatial spectrum estimation to enhance the degrees-of-freedom (DOFs) …
