Low-Complexity Channel Estimation for Massive MIMO Systems with Decentralized Baseband Processing
Yanqing Xu, Bo Wang, Enbin Song +2
The traditional centralized baseband processing architecture is faced with the bottlenecks of high computation complexity and excessive fronthaul communication, especially when the…
Optimal Resource Allocation for Delay Minimization in NOMA-MEC Networks
Fang Fang, Yanqing Xu, Zhiguo Ding +3
Multi-access edge computing (MEC) can enhance the computing capability of mobile devices, while non-orthogonal multiple access (NOMA) can provide high data rates. Combining these t…
Energy-Efficient Design of IRS-NOMA Networks
Fang Fang, Yanqing Xu, Quoc-Viet Pham +1
Combining intelligent reflecting surface (IRS) and non-orthogonal multiple access (NOMA) is an effective solution to enhance communication coverage and energy efficiency. In this p…
Intelligent User Clustering and Robust Beamforming Design for UAV-NOMA Downlink
Yanqing Xu, Fang Fang, Donghong Cai +1
In this work, we consider a downlink NOMA network with multiple single-antenna users and multi-antenna UAVs. In particular, the users are spatially located in several clusters by f…
HARQ-CC Enabled NOMA Designs With Outage Probability Constraints
Yanqing Xu, Donghong Cai, Fang Fang +3
In this paper, we aim to design an adaptive power allocation scheme to minimize the average transmit power of a hybrid automatic repeat request with chase combining (HARQ-CC) enabl…
Physical Layer Security in UAV Systems: Challenges and Opportunities
Xiaofang Sun, Derrick Wing Kwan Ng, Zhiguo Ding +2
Unmanned aerial vehicle (UAV) wireless communications have experienced an upsurge of interest in both military and civilian applications, due to its high mobility, low cost, on-dem…
