Space-shift-keying (SSK) and spatial modulation (SM) enable multiple antenna transmission systems to convey information on antenna indices. While SSK/SM helps reduce the number of radio frequency (RF) chains, large numbers of antennas and low spatial

MU-MIMO transmission relies on exploiting multi-user diversity among a multitude of users. In this paper, to enhance MU-MIMO transmission, techniques for designing and exploiting reconfigurable antennas (RAs) are developed. A single-element RA is cap

Multifunctional and reconfigurable multiple-input multiple-output (MR-MIMO) antennas are capable of dynamically changing the operation frequencies, polarizations, and radiation patterns, and can remarkably enhance system capabilities. However, in coh
In this paper, a downlink wireless communication channel is considered. The base station (BS) has common data for all users, unicast data for a set of intended users, and transmits the superposition of these messages. This setting neither falls into

This paper proposes an efficient downlink multi- user MIMO (MU-MIMO) scheme for multiple antenna transmission systems comprised of reconfigurable antenna (RA) elements. MU-MIMO schemes typically require a combined user pairing and precoding scheme wh

Over-the horizon wireless communications within the HF-band is subject to the Faraday effect where the polarization of electromagnetic waves rotates due to the ionization and geomagnetic interactions. This results in further signal loss and fading in

Direction of arrival (DoA) estimation is one of the key issues for many radar and wireless communications applications. In those applications, a major drawback is the presence of multiple paths resulting in highly correlated received signals. Spatial
