Frame-Based AFDM-ISAC Waveform Design With Chirp-Enabled Pulse Compression
Qu Luo, Zilong Liu, Musavian Leila +3
This paper proposes an Affine frequency division multiplexing (AFDM)-empowered integrated sensing and communications (ISAC) design, referred to as AFDM-ISAC. We first design a nove…
Spatially Coupled Sparse Code Multiple Access (SC-SCMA): A Spectral Graph Approach
Yiming Gui, Zilong Liu, Qu Luo +1
This paper presents a spatially coupled sparse code multiple access (SC-SCMA) framework to overcome the performance and scalability limitations of conventional SCMA systems. By ana…
Low Complexity Weight Flexible Decoding Schemes of Linear Block Code for 6G xURLLC
Di Zhang, Yinglei Yang, Zilong Liu +3
Low complexity error correction code is a key enabler for next generation ultra-reliable low-latency communications (xURLLC) in six generation (6G). Against this background, this p…
Joint Sparse Graph for Enhanced MIMO-AFDM Receiver Design
Qu Luo, Jing Zhu, Zilong Liu +4
Affine frequency division multiplexing (AFDM) is a promising chirp-assisted multicarrier waveform for future high-mobility communications. This paper is devoted to enhanced receive…
Deep Learning Assisted Multiuser MIMO Load Modulated Systems for Enhanced Downlink mmWave Communications
Ercong Yu, Jinle Zhu, Qiang Li +4
This paper is focused on multiuser load modulation arrays (MU-LMAs) which are attractive due to their low system complexity and reduced cost for millimeter wave (mmWave) multi-inpu…
A Tutorial on Decoding Techniques of Sparse Code Multiple Access
Saumya Chaturvedi, Zilong Liu, Vivek Ashok Bohara +2
Sparse Code Multiple Access (SCMA) is a disruptive code-domain non-orthogonal multiple access (NOMA) scheme to enable \color{black}future massive machine-type communication network…
