We propose and analyze transmit antenna selection (TAS) to enhance physical layer
security in a wiretap channel with NA antennas at the transmitter, NB antennas at the …

A multiuser dual-hop relaying system over mixed radio frequency/free-space optical
(RF/FSO) links is investigated. Specifically, the system consists of m single-antenna sources …

In this paper, the performance of an uncoded multiple-input-multiple-output (MIMO) scheme
combining single transmit antenna selection and receiver maximal-ratio combining (the …

This paper investigates the secrecy outage performance of transmit antenna selection
(TAS)/maximal ratio combining (MRC) in multiple-input-multiple-output (MIMO) cognitive …

We evaluate the performance of downlink multiuser relay networks (MRNs) equipped with a
single amplify-and-forward (AaF) relay. A thorough and exact analysis is conducted to …

We propose and analyze two multiple-input-multiple-output (MIMO) two-way relaying
schemes with an amplify-and-forward protocol in Nakagami-m fading channels, where multi …

This paper gives an insight on the performance of mixed dual-hop radio-frequency (RF)-
underwater optical wireless communication (UOWC) systems. The system consists of …

Free-space optics (FSO) communication is often unreliable, especially for long distances, as
it suffers from attenuation due to foggy weather, atmospheric turbulence, and pointing errors …

In this paper, we propose two relay antenna selection (RAS) schemes in multiple-input-
multiple-output (MIMO) two-way relay networks, where an N A-antenna source and an N B …

In this paper, we study the outage performance of multiuser mixed underlay radio frequency
(RF)/multidestinations free-space optical (FSO) links. For RF links, we consider a secondary …
