recommendations! Published in 2020 at "IEEE Transactions on Communications"

DOI: 10.1109/tcomm.2020.2981079

Abstract: We consider a relay-assisted non-orthogonal multiple access (NOMA) network consisting of a source (S), an energy-constrained relay (R), and two users, where a hybrid power-splitting (PS) and time-splitting (TS) scheme is applied at R for… read more here.

DOI: 10.1109/tvt.2021.3064610

Abstract: This paper proposes a stochastic-robust constructive interference (CI) precoding scheme for downlink multi-user MISO systems, assuming that channel state information (CSI) at the transmitter side (CSIT) is contaminated by Gaussian-distributed uncertainties. Our objective is to… read more here.

recommendations! Published in 2024 at "IEEE Transactions on Wireless Communications"

DOI: 10.1109/twc.2024.3395670

Abstract: The growth of vehicular applications will inevitably require Base Stations (BSs) to simultaneously serve more Connected Vehicles (CVs) within limited bandwidth resources, which imposes a great challenge in interference management. Effective management of this interference… read more here.
