Cooperative MARL-Based Energy-Efficient Power Control for Two-Hop Relaying Networks
Xinyu Qu, Yuanzhe Geng, Erwu Liu +1
In this paper, we study a cooperative game in the cooperative communication network, where each relay makes decisions autonomously and aims to achieve the same optimization objecti…
Effect of Antenna Deployment on Achievable Rate in Cooperative Magnetic Induction Communication
Honglei Ma, Erwu Liu, Rui Wang +1
The paper proposes a cooperative magnetic induction (CMI) communication scheme using an amplify‑and‑forward relay and derives closed‑form formulas for the achievable data‑rate gain…
Antenna Optimization for Decode-and-Forward Relay in Magnetic Induction Communications
Honglei Ma, Erwu Liu, Rui Wang +4
Magnetic Induction (MI) communication is effective in underground tunnels for emergency rescue vehicle due to the small-size antenna. It can highly benefit from a cooperative decod…
Reconfigurable Intelligent Surface-Assisted Localization in OFDM Systems with Carrier Frequency Offset and Phase Noise
Hanfu Zhang, Erwu Liu, Rui Wang +4
Reconfigurable intelligent surface (RIS)-assisted communication systems have been extensively studied for providing high-precision location services. However, most studies have ove…
