Intelligent Power Control for Spectrum Sharing in Cognitive Radios: A Deep Reinforcement Learning Approach
Xingjian Li, Jun Fang, Wen Cheng +3
We consider the problem of spectrum sharing in a cognitive radio system consisting of a primary user and a secondary user. The primary user and the secondary user work in a non-coo…
Physical Layer Service Integration in 5G: Potentials and Challenges
Weidong Mei, Zhi Chen, Jun Fang +1
High transmission rate and secure communication have been identified as the key targets that need to be effectively addressed by fifth generation (5G) wireless systems. In this con…
Artificial Noise-Aided Biobjective Transmitter Optimization for Service Integration in Multi-User MIMO Gaussian Broadcast Channel
Weidong Mei, Zhi Chen, Jun Fang +1
This paper considers an artificial noise (AN)-aided transmit design for multi-user MIMO systems with integrated services. Specifically, two sorts of service messages are combined a…
Compressive Channel Estimation and Multi-user Detection in C-RAN
Qi He, Tony Q. S. Quek, Zhi Chen +1
This paper considers the channel estimation (CE) and multi-user detection (MUD) problems in cloud radio access network (C-RAN). Assuming that active users are sparse in the network…
