Probabilistic ODMA Receiver with Low-Complexity Algorithm for MIMO Unsourced Random Access
Zhentian Zhang, Jian Dang, Zaichen Zhang
In this work, we present the design for both pilot-uncoupled and pilot-free on-off multiple access (ODMA) receivers in unsourced random access (URA) for multiple-input multiple-out…
Sparse Code Transceiver Design for Unsourced Random Access with Analytical Power Division in Gaussian MAC
Zhentian Zhang, Mohammad Javad Ahmadi, Jian Dang +3
In this work, we discuss the problem of unsourced random access (URA) over a Gaussian multiple access channel (GMAC). To address the challenges posed by emerging massive machine-ty…
Sparsity-Exploiting Channel Estimation For Unsourced Random Access With Fluid Antenna
Keru Zhou, Zhentian Zhang, Jian Dang +2
This work explores the channel estimation (CE) problem in uplink transmission for unsourced random access (URA) with a fluid antenna receiver. The additional spatial diversity in a…
Integrated Sensing and Communications for Unsourced Random Access: A Spectrum Sharing Compressive Sensing Approach
Zhentian Zhang, Jian Dang, Kai-Kit Wong +2
This paper addresses the unsourced/uncoordinated random access problem in an integrated sensing and communications (ISAC) system, with a focus on uplink multiple access code design…
Downlink Precoding for Cell-free FBMC/OQAM Systems With Asynchronous Reception
Yuhao Qi, Jian Dang, Zaichen Zhang +2
In this work, an efficient precoding design scheme is proposed for downlink cell-free distributed massive multiple-input multiple-output (DM-MIMO) filter bank multi-carrier (FBMC)…
