Secrecy of Multi-Antenna Transmission with Full-Duplex User in the Presence of Randomly Located Eavesdroppers
Ishmam Zabir, Ahmed Maksud, Gaojie Chen +2
This paper considers the secrecy performance of several schemes for multi-antenna transmission to single-antenna users with full-duplex (FD) capability against randomly distributed…
Hybrid Multicast/Unicast Design in NOMA-based Vehicular Caching System with Supplementary Material
Xinyue Pei, Hua Yu, Yingyang Chen +2
In this paper, we investigate a hybrid multicast/ unicast scheme for a multiple-input single-output cache-aided non-orthogonal multiple access (NOMA) vehicular scenario in the face…
Delay Constrained Buffer-Aided Relay Selection in the Internet of Things with Decision-Assisted Reinforcement Learning
Chong Huang, Gaojie Chen, Yu Gong
This paper investigates the reinforcement learning for the relay selection in the delay-constrained buffer-aided networks. The buffer-aided relay selection significantly improves t…
Random Shifting Intelligent Reflecting Surface for OTP Encrypted Data Transmission
