On the Error Exponent of Amplify and Forward Relay Networks

IEEE Communications Letters, 2011
In this letter we derive the exact random coding error exponent of a dual hop amplify and forward (AF) relay network with channel state information (CSI) assisted ideal relay gain. Numerical results have been presented, which provide insight about the performance tradeoff between the error exponent and the data rate of the network.

Outage optimality of opportunistic amplify-and-forward relaying

IEEE Communications Letters, 2007
In this paper, we show that optimal selection and transmission of a single relay among a set of multiple amplify-and-forward (AF) candidates minimize the outage probability (i.e., outage-optimal) and outperform any other strategy that involves simultaneous transmissions from more than one AF relay under an aggregate power constraint.

An amplify-and-forward scheme for cognitive radios

2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014
In this paper, we propose an opportunistic amplify-and-forward relaying scheme for a cognitive radio network, which is aimed at allowing a secondary user (SU) to transmit over the same timefrequency slot of a primary user (PU). In our scheme, the SU amplifies and transmits the PU signal it receives, by using as relaying gain the information symbols ...
