Next-generation cellular technologies, commonly referred to as the sixth generation (6G),
are envisioned to support a higher system capacity, better performance, and network …

Different from phased array providing only angle‐dependent transmit beampattern,
frequency diverse array (FDA) employs a small frequency increment across its array …

In order to estimate the signal parameters accurately for mobile systems, it is necessary to
estimate a system's propagation characteristics through a medium. Propagation analysis …

This paper links the direct-sequence code-division multiple access (DS-CDMA) multiuser
separation-equalization-detection problem to the parallel factor (PARAFAC) model, which is …

In wireless networks, an essential step for precise range-based localization is the high-
resolution estimation of multipath channel delays. The resolution of traditional delay …

In a parametric multipath propagation model, a source is received by an antenna array via a
number of rays, each described by an arrival angle, a delay, and a fading parameter. Unlike …

The use of the millimeter (mm) wave spectrum for next generation (5G) mobile
communication has gained significant attention recently. The small carrier wavelengths at …

A new efficient algorithm is presented for joint diagonalization of several matrices. The
algorithm is based on the Frobenius-norm formulation of the joint diagonalization problem …

This paper proposes a closed-loop sparse channel estimation (CE) scheme for wideband
millimeter-wave hybrid full-dimensional multiple-input multiple-output and time division …

In this paper, we consider two-dimensional (2-D) signals modeled by the sum of damped
cisoids. We propose two high-resolution approaches to estimate their frequencies and …
