Subcarrier pairing for amplify-and-forward and decode-and-forward OFDM relay links
IEEE Communications Letters, 2009We consider a two-hop relay link in which orthogonal frequency division multiplexing (OFDM) is used on both hops. Under a joint sum-power constraint, our aim is to allocate power over subcarriers on the two hops such that the instantaneous rate of the relay link is maximized.

Noncoherent Detection in Amplify-and-Forward Relay Systems
IEEE GLOBECOM 2008 - 2008 IEEE Global Telecommunications Conference, 2008In amplify-and-forward single-relay systems that employ an average relay power constraint, one-shot detection at the destination terminal is not optimal when the channel between the source and relay terminals is unknown. In this work, we derive the maximum-likelihood (ML) block noncoherent detector and show that it can be expressed as a reduced-rank ...

Jamming in Dual-Hop Amplify-and-Forward Relaying
IEEE Transactions on Vehicular Technology, 2015The performance of a dual-hop amplify-and-forward (AF) relaying system in the presence of a jammer is analyzed by obtaining the end-to-end outage probability for the scenario where the system is interference limited and operates in either Nakagami-0.5 or Rayleigh fading environments.

Compressed cooperation in an amplify-and-forward relay channel
2015 IEEE 26th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2015The theory of compressed sensing (CS) is very attractive in that it is possible to reconstruct sparse signals with a sub-Nyquist sampling rate. Recently many researches have applied CS as the channel code, and show its great potential in communication systems. This paper studies the compressed cooperation in an amplify-and-forward (CC-AF) relay channel,

A Practical Differential Receiver for Amplify-and-Forward Relaying
IEEE Wireless Communications Letters, 2014A practical sequence detector of differential phase-shift keying (DPSK) is developed in closed-form for amplify-and-forward (AF) cooperative networks. This detector is applicable for general M-DPSK (M ≥ 2) with arbitrary sequence length N 8 ≥ 1, which includes a single-by-symbol detector as a special case N 8 = 1.
