In this paper, we formulate an optimization problem for secure resource allocation and
scheduling in orthogonal frequency division multiple access (OFDMA) half-duplex decode …

We propose a new optimal location-based beamforming (LBB) scheme for the wiretap
channel, where both the main channel and the eavesdropper's channel are subject to Rician …

This paper proposes a new channel training (CT) scheme for a full-duplex receiver to
enhance physical layer security. Equipped with NB full-duplex antennas, the receiver …

Recently, substantial attention has been paid to increase the achievable rates of wireless
networks using different kinds of limited channel quality information feedback. Hybrid …

Antenna selection in Multiple-Input-Multiple-Output (MIMO) systems preserves diversity gain
while significantly reducing hardware complexity. However, imperfect Channel State …

We consider a multi-input single-output visible light communication (MISO-VLC) system. For
such system under both average and peak optical power constraint, an optimal space …

We study opportunistic multiuser scheduling in downlink networks with Markov-modeled
outage channels. We consider the scenario that the scheduler does not have full knowledge …

Randomness test suites constitute an essential component within the process of assessing
random number generators in view of determining their suitability for a specific application …

This paper focuses on the downlink of a cellular system and studies opportunistic multiuser
scheduling under imperfect channel state information, by exploiting the memory inherent in …

While the impact of finite-rate feedback on the capacity of fading channels has been
extensively studied in the literature, not much attention has been paid to this problem under …
