In this article, channel estimation for millimeter-wave massive multiple-input–multiple-output
(MIMO) systems with hybrid beamforming is considered. With a large number of antenna …

This article introduces a multiemitter 2-D angle-of-arrival (AoA) estimation scheme. It
consists of an AoA estimation algorithm based on impinging signal spatial sparsity, Dantzig …

A precise incident wave angle estimation in aerial communication is a key enabler in sixth-
generation wireless communication network. With this goal, a generic 3-dimensional (3D) …

This article presents the hardware implementation and a behavioral model-based RF
system modeling and simulation (M&S) study of compressive sensing (CS) based 2D angle …

In this paper, the problem of direction-of-arrival (DoA) estimation for a hybrid array of
subarrays is considered in millimeter-wave communication systems. Unlike much prior work …

Constant modulus algorithm (CMA) has been widely used in direction of arrival (DOA)
estimation for constant modulus signals. However, CMA fails completely when dealing with …

This paper introduces a 2D angle‐of‐arrival (AoA) estimator, which has a 6–18 GHz 7‐
element nonuniformly spaced array (NSA) and a Direct Data Domain‐(D3‐) based AoA …

Estimating the accurate Angle-of-Aarrival (AOA) of a signal is one of the important issues of
a modern wireless communication system based on beamforming. AOA of the signal is …
