Free-space optical (FSO) links are contemplated as a potential paradigm to yield efficient
point-to-point communication in wireless systems. Notably, these links are used to provide …

Orthogonal frequency division multiplexing (OFDM) is considered as a key technology for
future wireless communication systems. One of the main disadvantages of OFDM systems is …

In this paper, a fixed‐gain amplify‐and‐forward relaying under non‐ideal hardware is
analyzed. The relaying system is impaired because of relay's power amplifier (PA) …

This paper studies the energy-limited performance of multi-relay networks. Taking the
properties of the power amplifiers (PAs) into account, we derive closed-form expressions for …

In this paper, the performance of the cooperative cognitive radio network with the amplify-
and-forward protocol is studied when the relay uses a nonlinear power amplifier (NLPA) …

In this paper, we analyze the symbol-error rate of a two-hop fixed-gain amplify-and-forward
OFDM relay network when nonlinear distortion, as a consequence of relay amplifier …

We consider the problem of allocating power among the nodes of a two-way amplify-and-
forward OFDM-based relay network employing physical layer network coding. Because of …

Due to the constraint of cost for relay nodes, nonlinear power amplifiers are employed in
wireless relay networks. In this paper, we investigate the effect of Traveling-Wave Tube …

This paper analyzes the downlink achievable spectral efficiency of an orthogonal frequency‐
division multiplexing (OFDM) cooperative cognitive network with a non‐linear relay. The …

This thesis examines the effects of resource constraints on amplify-and-forward (AF)
networks. Chapters 3 and 4 are the first research chapters. Chapter 3 studies the outage …
