Piggybacking Codes for Network Coding: The High/Low SNR Regime
, 2017 We propose a piggybacking scheme for network coding where strong source inputs piggyback the weaker ones, a scheme necessary and sufficient to achieve the cut-set upper bound at high/low-snr regime, a new asymptotically optimal operational regime for the

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

Amplify-and-Forward Gateway With Zero-Forcing in Multiuser Environments [PDF]
IEEE Transactions on Vehicular Technology, 2017 In this paper, we investigate and analyze the performance of amplify and forward (AF) gateways employing zero-forcing (ZF) beamforming techniques in a space division multiple access (SDMA) scenario. A random number of users are isolated from their destination(s) and the only means to communicate with their destination(s) is through the AF gateway ...

Secure Multiple Amplify-and-Forward Relaying With Cochannel Interference [PDF]
IEEE Journal of Selected Topics in Signal Processing, 2016 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 ...

Interference Channel With Full-Duplex Amplify-and-Forward Transmitter Cooperations
IEEE Access, 2019 This paper considers a Gaussian interference channel (IC), where two transmitters send two messages to two receivers respectively. By utilizing the in-band full-duplex (FD) amplify-and-forward (AF) scheme, transmitter cooperations are deployed to enhance
