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…
Asymptotically Optimal Sequence Sets With Low/Zero Ambiguity Zone Properties
Liying Tian, Xiaoshi Song, Zilong Liu +1
Sequences with low/zero ambiguity zone (LAZ/ZAZ) properties are useful in modern communication and radar systems operating over mobile environments. This paper first presents a new…
Joint Beamforming Design for Integrated Sensing and Communication Systems with Hybrid-Colluding Eavesdroppers
Meiding Liu, Zhengchun Zhou, Qiao Shi +4
In this paper, we consider the physical layer security (PLS) problem for integrated sensing and communication (ISAC) systems in the presence of hybrid-colluding eavesdroppers, wher…
Phase Noise Resilient Codebook Design for Sparse Code Multiple Access
Haibo Liu, Qu Luo, Zilong Liu +3
Sparse code multiple access (SCMA) is a promising technique for future machine type communication systems due to its superior spectral efficiency and capability for supporting mass…
