Determining the number of sources from observed data is a fundamental problem in many
scientific fields. In this paper we consider the nonparametric setting, and focus on the …

Numerous methodologies have been investigated for source enumeration in sample-
starving environments. For those having their root in the framework of random matrix theory …

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 …

The increasing of illegal radiations, which are either artificial or unintentional, has seriously
influenced the reliable communication and operation of industrial facilities. In this article, we …

A novel pseudo-noise resampling (PR) based unitary root-MUSIC algorithm for direction-of-
arrival (DOA) estimation is derived in this letter. Our solution is able to eliminate the …

This article addresses the problem of direction of arrival (DOA) estimation only relying on the
sign bits of the array signal. A new optimization model is formulated to realize the …

High-resolution parameter estimation algorithms designed to exploit the prior knowledge
about incident signals from strictly second-order (SO) noncircular (NC) sources allow for a …

One-bit direction of arrival (DOA) estimation has received considerable attention in recent
years due to its ability to reduce complexity, cost, and storage in radar and wireless …

Source enumeration is typically studied under the assumption of white noise, which may not
be suitable for real-world applications. In this article, a source enumeration algorithm robust …

Although linearly constrained minimum variance (LCMV) beamforming is robust against
imprecise target information, it usually leads to relatively high sidelobe and distorted …
