A Novel HARQ-CC Assisted SCMA Scheme
Man Wang, Zheng Shi, Yunfei Li +3
This letter proposes a novel hybrid automatic repeat request with chase combining assisted sparse code multiple access (HARQ-CC-SCMA) scheme. Depending on whether the same superimp…
Variational Bayesian Learning Based Localization and Channel Reconstruction in RIS-aided Systems
Yunfei Li, Yiting Luo, Xianda Wu +3
The emerging immersive and autonomous services have posed stringent requirements on both communications and localization. By considering the great potential of reconfigurable intel…
Variational Bayesian Learning based Joint Localization and Path Loss Exponent with Distance-dependent Noise in Wireless Sensor Network
Yunfei Li, Yiting Luo, Weiqiang Tan +3
This paper focuses on the challenge of jointly optimizing location and path loss exponent (PLE) in distance-dependent noise. Departing from the conventional independent noise model…
Outage Probability Analysis of HARQ-Aided Terahertz Communications
Ziyang Song, Zheng Shi, Qingping Dou +3
Although terahertz (THz) communications can provide mobile broadband services, it usually has a large path loss and is vulnerable to antenna misalignment. This significantly degrad…
