Hybrid Beamforming for Subarray-Level Movable Antenna Enhanced MU-MIMO Communications
Shanshan Zhang, Songjie Yang, Wenxuan Zhang +2
This study investigates subarray-level movable antenna (MA) architecture for multi-user MIMO (MU-MIMO) systems. Unlike conventional systems with fixed-position antennas (FPAs), the…
Fairness Optimization for Intelligent Reflecting Surface Aided Uplink Rate-Splitting Multiple Access
Shanshan Zhang, Wen Chen, Qingqing Wu +3
This paper studies the fair transmission design for an intelligent reflecting surface (IRS) aided rate-splitting multiple access (RSMA). IRS is used to establish a good signal prop…
Rate-Splitting Multiple Access for Transmissive Reconfigurable Intelligent Surface Transceiver Empowered ISAC System
Ziwei Liu, Wen Chen, Qingqing Wu +4
In this paper, a novel transmissive reconfigurable intelligent surface (TRIS) transceiver empowered integrated sensing and communications (ISAC) system is proposed for future multi…
Fairness Optimization of RSMA for Uplink Communication based on Intelligent Reflecting Surface
Shanshan Zhang, Wen Chen
In this paper, we propose a rate-splitting multiple access (RSMA) scheme for uplink wireless communication systems with intelligent reflecting surface (IRS) aided. In the considere…
Joint Device Activity Detection, Channel Estimation and Signal Detection for Massive Grant-free Access via BiGAMP
Shanshan Zhang, Ying Cui, Wen Chen
Massive access has been challenging for the fifth generation (5G) and beyond since the abundance of devices causes communication overload to skyrocket. In an uplink massive access…
Joint Transceiver Design Based on Dictionary Learning Algorithm for SCMA
Shanshan Zhang, Wen Chen, Shaoyuan Chen
With the explosively increasing demands on the network capacity, throughput and number of connected wireless devices, massive connectivity is an urgent problem for the next generat…
