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)…
Clustering-Based Codebook Design for MIMO Communication System
Jing Jiang, Xiaojing Wang, Guftaar Ahmad Sardar Sidhu +2
Codebook design is one of the core technologies in limited feedback multi-input multi-output (MIMO) communication systems. However, the conventional codebook designs usually assume…
Practical Analysis of Codebook Design and Frequency Offset Estimation for Virtual-MIMO Systems
Jing Jiang, John S. Thompson, Hongjian Sun +1
A virtual multiple-input multiple-output (MIMO) wireless system using the receiver-side cooperation with the compress-and-forward (CF) protocol, is an alternative to a point-to-poi…
Relaying Technologies for Smart Grid Communications
Hongjian Sun, Bo Tan, Jing Jiang +3
Wireless technologies can support a broad range of smart grid applications including advanced metering infrastructure (AMI) and demand response (DR). However, there are many formid…
