Large-Scale Rate-Splitting Multiple Access in Uplink UAV Networks: Effective Secrecy Throughput Maximization Under Limited Feedback Channel [PDF]
IEEE Transactions on Vehicular Technology, 2023 UAVs are capable of improving the performance of next generation wireless systems. Specifically, UAVs can be exploited as aerial base-stations (UAV-BS) for supporting legitimate ground users in remote uncovered areas or in environments temporarily requiring high capacity.

Journal of Communication and Information Systemsl, 2021 This study discusses an augmented investigation of the hybrid wiretap channel, which represents a PLC system with its data security threatened by a malicious and passive wireless device at the physical layer level, by focusing on the evaluation and analysis of wiretap code rates. The wiretap code rates are obtained through effective secrecy throughput.
