Designing Enhanced Multi-dimensional Constellations for Code-Domain NOMA
Haifeng Wen, Zilong Liu, Qu Luo +2
This paper presents an enhanced design of multi-dimensional (MD) constellations which play a pivotal role in many communication systems such as code-domain non-orthogonal multiple…
Simultaneous Transmission and Reflection Reconfigurable Intelligent Surface Assisted MIMO Systems
Hehao Niu, Zheng Chu, Fuhui Zhou +2
In this work, we investigate a novel simultaneous transmission and reflection reconfigurable intelligent surface (RIS)-assisted multiple-input multiple-output downlink system, wher…
A Tutorial to Sparse Code Multiple Access
Saumya Chaturvedi, Zilong Liu, Vivek Ashok Bohara +2
Sparse Code Multiple Access (SCMA) is an enabling code-domain non-orthogonal multiple access (NOMA)scheme for massive connectivity and ultra low-latency in future machine-type comm…
A Novel Transmission Policy for Intelligent Reflecting Surface Assisted Wireless Powered Sensor Networks
Zheng Chu, Pei Xiao, De Mi +3
This paper proposes a novel transmission policy for an intelligent reflecting surface (IRS) assisted wireless powered sensor network (WPSN). An IRS is deployed to enhance the perfo…
