On Secure NOMA-CDRT Systems with Physical Layer Network Coding
Hongjiang Lei, Xusheng She, Ki-Hong Park +4
This paper proposes a new scheme to enhance the secrecy performance of a NOMA-based coordinated direct relay transmission system (NOMA-CDRT) with an untrusted relay. The physical-l…
Joint Trajectory Design and User Scheduling of Aerial Cognitive Radio Networks
Hongjiang Lei, Haosi Yang, Ki-Hong Park +3
Unmanned aerial vehicles (UAVs) have been widely employed to enhance the end-to-end performance of wireless communications since the links between UAVs and terrestrial nodes are li…
Uplink Performance of High-Mobility Cell-Free Massive MIMO-OFDM Systems
Jiakang Zheng, Jiayi Zhang, Enyu Shi +2
High-speed train (HST) communications with orthogonal frequency division multiplexing (OFDM) techniques have received significant attention in recent years. Besides, cell-free (CF)…
