Joint Transmit and Receive Beamforming for Tri-directional Coil-Based Magnetic Induction Communications
Jinyang Li, Jianyu Wang, Wenchi Cheng +2
In this paper, we enhance the omnidirectional coverage performance of tri-directional coil-based magnetic induction communication (TC-MIC) and reduce the pathloss with a joint tran…
Multi-Frequency Resonant Circuit Based Multi-User Emergency Through-the-Earth Communication with Magnetic Induction
Zhenyu Wang, Jianyu Wang, Wenchi Cheng
Magnetic induction (MI) is an effective technique in emergency through-the-earth communications due to the higher penetration efficiency and lower propagation loss as compared with…
Virtual Full-Duplex Wireless Communications with Zero-Interval Modulation and Sampling
Jianyu Wang, Wenchi Cheng, Wei Zhang +1
In this paper, we propose a virtual full-duplex (VFD) technique with zero-interval modulation and sampling (ZIMS), where two half-duplex (HD) transceivers can simultaneously transm…
RIS-Based Self-Interference Cancellation for Full-Duplex Broadband Transmission
Jiayan Wu, Wenchi Cheng, Jianyu Wang +2
Full-duplex (FD) is an attractive technology that can significantly boost the throughput of wireless communications. However, it is limited by the severe self-interference (SI) fro…
