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)…
A Low-Complexity ADMM-based Massive MIMO Detectors via Deep Neural Networks
Isayiyas Nigatu Tiba, Quan Zhang, Jing Jiang +1
An alternate direction method of multipliers (ADMM)-based detectors can achieve good performance in both small and large-scale multiple-input multiple-output (MIMO) systems. Howeve…
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…
Multi-User Hybrid Precoding for Dynamic Subarrays in MmWave Massive MIMO Systems
Jing Jiang, Yue Yuan, Li Zhen
Dynamic subarray achieves a compromise between sum rate and hardware complexity for millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) systems in which antenna…
