Asymptotically Optimal Aperiodic and Periodic Sequence Sets with Low Ambiguity Zone Through Locally Perfect Nonlinear Functions
Zheng Wang, Zhengchun Zhou, Avik Ranjan Adhikary +3
Low ambiguity zone (LAZ) sequences play a crucial role in modern integrated sensing and communication (ISAC) systems. In this paper, we introduce a novel class of functions known a…

Oversampled Low Ambiguity Zone Sequences for Channel Estimation over Doubly Selective Channels
Zhi Gu, Zhengchun Zhou, Pingzhi Fan +2
Pilot sequence design over doubly selective channels (DSC) is challenging due to the variations in both the time- and frequency-domains. Against this background, the contribution o…
