The increasing use of relays in underwater acoustic (UWA) communications is a driving
force to explore efficient techniques that can significantly improve the system performance …

In this article, we propose a cross-layer resource management mechanism for an indoor
multiuser visible light communication (VLC) access network. The physical layer builds upon …

Atmospheric turbulence is a major degrading factor in free-space optical (FSO) systems.
Since turbulence-induced fading results in a very slowly-varying channel, reliable feedback …

In this paper, we investigate the performance of an amplify-and-forward (AF) cooperative
diversity system with multiple relays in the presence of channel estimation errors. We …

This paper addresses the area of heterogeneous wireless relaying vehicular clouds. We
devise an advanced vehicular relaying technique for enhanced connectivity in densely …

In this paper, we present a channel estimation scheme for Amplify-and-Forward (AF)
relaying systems, using measurements at the destination only. A Least-Squares (LS) based …

This paper investigates the channel estimations in a relay network with multiple transmit and
receive antennas, including the estimation of the end-to-end channel matrix and the …

Bit error rate (BER) and outage probability for amplify-and-forward (AF) relaying systems
with two different channel estimation methods, disintegrated channel estimation and …

In this paper, we investigate bit and power allocation strategies for an orthogonal frequency
division multiplexing (OFDM) cooperative network over frequency-selective fading channels …

In this paper, we design a segment training based individual channel estimation (STICE)
scheme in the classical three-node it amplify-and-forward (AF) one-way relay network …
