Proximal Policy Optimization-based Transmit Beamforming and Phase-shift Design in an IRS-aided ISAC System for the THz Band

no code implementations21 Mar 2022 Xiangnan Liu, Haijun Zhang, Keping Long, Mingyu Zhou, Yonghui Li, H. Vincent Poor

Then the joint optimization of transmit beamforming and phase-shift design is achieved by gradient-based, primal-dual proximal policy optimization (PPO) in the multi-user multiple-input single-output (MISO) scenario.

AI-aided Traffic Control Scheme for M2M Communications in the Internet of Vehicles

no code implementations5 Mar 2022 Haijun Zhang, Minghui Jiang, Xiangnan Liu, Keping Long, Victor C. M. Leung

Due to the rapid growth of data transmissions in internet of vehicles (IoV), finding schemes that can effectively alleviate access congestion has become an important issue.

Decentralized Baseband Processing with Gaussian Message Passing Detection for Uplink Massive MU-MIMO Systems

no code implementations22 May 2021 Zhenyu Zhang, Yuanyuan Dong, Keping Long, Xiyuan Wang, Xiaoming Dai

Decentralized baseband processing (DBP) architecture, which partitions the base station antennas into multiple antenna clusters, has been recently proposed to alleviate the excessively high interconnect bandwidth, chip input/output data rates, and detection complexity for massive multi-user multiple-input multiple-output (MU-MIMO) systems.

Energy Efficient User Clustering, Hybrid Precoding and Power Optimization in Terahertz MIMO-NOMA Systems

no code implementations3 May 2020 Haijun Zhang, Haisen Zhang, Wei Liu, Keping Long, Jiangbo Dong, Victor C. M. Leung

Considering the power consumption and implementation complexity, the hybrid precoding scheme based on the sub-connection structure is adopted.
