Localizing Noncooperative Receiver Through Full-Duplex Amplify-and-Forward Relay
IEEE Access, 2018 Localizing noncooperative transmitter (Tx) and receiver (Rx) that belong to another system is important in many scenarios, e.g., interference management in cognitive radio systems and user behavior learning in ad hoc wireless networks. However, obtaining

Frequency Offset Amplify-and-Forward Relay in OFDM System
IEICE Transactions on Communications, 2011 In the fourth generation mobile communication system, the frequency band higher than the bands already used for IMT-2000 has been assigned. However, the higher radio frequency increases the propagation loss. To cope with the propagation loss, relay transmission has been investigated.

Relay Switching Aided Turbo Coded Hybrid-ARQ for Correlated Fading Channel
, 2011 Hybrid-Automatic-Repeat-reQuest (HARQ) has become an indispensable technique in reliable communications systems. However, its performance is inevitably affected by the channel’s fading correlation. In this paper, we proposed a novel relay-switching aided

SINR Maximizing Beamforming Schemes for the Full Duplex Amplify-and-Forward Relay Channel
IEEE Access, 2017 We propose signal-to-interference-plus-noise power ratio (SINR) maximizing rank one beamforming schemes for the full-duplex (FD) relay systems. The non-regenerative amplify and forward (AaF) relay is considered with multiple transmit antennas and ...

Covert Communications in a Hybrid DF/AF Relay System
SensorsIn this paper, we study covert communications in a hybrid decode-and-forward (DF)/ amplify-and-forward (AF) relay system. The considered relay in normal operation forwards messages from a source node to a destination node in either DF or AF mode on ...

Efficient Simulation of the Outage Probability of Multihop Systems
IEEE Photonics Journal, 2017 In this paper, we present an efficient importance sampling estimator for the evaluation of the outage probability of multihop systems with amplify-and-forward channel state-information-assisted. The proposed estimator is endowed with the bounded relative
