Secure Multiple Amplify-and-Forward Relaying With Cochannel Interference [PDF]
We investigate the impact of cochannel interference on the security performance of multiple amplify-and-forward (AF) relaying networks, where $N$ intermediate AF relays assist the data transmission from the source to the destination. The relays are corrupted by multiple cochannel interferers, and the information transmitted from the relays to the ...

EM based channel estimation in an amplify-and-forward relaying network [PDF]
Cooperative communication offers a way to obtain spatial diversity in a wireless network without increasing hardware demands. The different cooperation protocols proposed in the literature [1] are often studied under the assumption that all channel state

Approaching Gaussian Relay Network Capacity in the High SNR Regime: End-to-End Lattice Codes [PDF]
We present a natural and low-complexity technique for achieving the capacity of the Gaussian relay network in the high SNR regime. Specifically, we propose the use of end-to-end structured lattice codes with the amplify-and-forward strategy, where the ...

Cooperative Spectrum Sensing Schemes with the Interference Constraint in Cognitive Radio Networks
In this paper, we propose cooperative spectrum sensing schemes, called decode-and-forward cooperative spectrum sensing (DF-CSS) scheme and amplify-and-forward cooperative spectrum sensing (AF-CSS) scheme, in cognitive radio networks.

An Efficient Partner Selection Method to Overcome the Interference Effect in Wireless Networks
In this paper, through a mathematical analysis of the overall links capacity equation, we present an efficient partner selection criterion in a cooperative communication scheme with a time-varying fading channel and severe interference on the cooperative

Differential Amplify-and-Forward Relaying in Time-Varying Rayleigh Fading Channels [PDF]
This paper considers the performance of differential amplify-and-forward (D-AF) relaying over time-varying Rayleigh fading channels. Using the auto-regressive time-series model to characterize the time-varying nature of the wireless channels, new weights
