Doppler Shift Keying Modulation for Uplink Multiple Access over Doubly-Dispersive Channels
Xuehan Wang, Jintao Wang, Hai Lin +4
The delay-Doppler (DD) domain modulation has been regarded as one of the most competitive candidates to support wireless communications for emerging high-mobility applications in t…
CSIYOLO: An Intelligent CSI-based Scatter Sensing Framework for Integrated Sensing and Communication Systems
Xudong Zhang, Jingbo Tan, Zhizhen Ren +3
ISAC is regarded as a promising technology for next-generation communication systems, enabling simultaneous data transmission and target sensing. Among various tasks in ISAC, scatt…
Age Optimal Sampling for Unreliable Channels under Unknown Channel Statistics
Hongyi He, Haoyue Tang, Jiayu Pan +3
In this paper, we study a system in which a sensor forwards status updates to a receiver through an error-prone channel, while the receiver sends the transmission results back to t…
Age of Synchronization Minimization in Wireless Networks with Random Updates and Time-Varying Timeliness Requirement
Yuqiao He, Yuchao Chen, Jintao Wang +1
This study considers a wireless network where multiple nodes transmit status updates to a base station (BS) via a shared, error-free channel with limited bandwidth. The status upda…
Input-Output Relation and Low-Complexity Receiver Design for CP-OTFS Systems with Doppler Squint
Xuehan Wang, Xu Shi, Jintao Wang +1
In orthogonal time frequency space (OTFS) systems, the impact of frequency-dependent Doppler which is referred to as the Doppler squint effect (DSE) is accumulated through longer d…
