MIMO-AFDM Outperforms MIMO-OFDM in the Face of Hardware Impairments
Zeping Sui, Zilong Liu, Leila Musavian +3
The impact of both multiplicative and additive hardware impairments (HWIs) on multiple-input multiple-output affine frequency division multiplexing (MIMO-AFDM) systems is investiga…
CDMA/OTFS Sensing Outperforms Pure OTFS at the Same Communication Throughput
Hugo Hawkins, Chao Xu, Lie-Liang Yang +1
There is a dearth of publications on the subject of spreading-aided Orthogonal Time Frequency Space (OTFS) solutions, especially for Integrated Sensing and Communication (ISAC), ev…
Generalized Spatial Modulation Aided Affine Frequency Division Multiplexing
Zeping Sui, Zilong Liu, Leila Musavian +2
Generalized spatial modulation-aided affine frequency division multiplexing (GSM-AFDM) is conceived for reliable multiple-input multiple-output (MIMO) communications over doubly se…
Heterogeneous graph neural network for power allocation in multicarrier-division duplex cell-free massive MIMO systems
Bohan Li, Lie-Liang Yang, Robert G Maunder +2
In-band full duplex cell-free (CF) systems suffer from severe self-interference and cross-link interference, especially when CF systems are operated in distributed way. To this end…
Carrier Phase Ranging for Indoor Positioning with 5G NR Signals
Liang Chen, Xin Zhou, Feifei Chen +2
Indoor positioning is one of the core technologies of Internet of Things (IoT) and artificial intelligence (AI), and is expected to play a significant role in the upcoming era of A…
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…
