Keyed-driven Integrated Sensing and Communication Waveform Design for Digital Twin Systems
摘要
Abstract
The deep integration of digital twin technology and unmanned aerial vehicle(UAV)applications is a crucial path to promote the high-quality development of the low-altitude economy.However,the high-speed and wide-area flight characteristics of UAVs make it a bottleneck in the construction of digital twin systems to simultaneously achieve the dual goals of reliable communication and accurate sensing.Therefore,a waveform design method for integrated sensing and communication(ISAC)based on weighted fractional Fourier transform is proposed.By integrating data transmission and radar sensing functions through cellular networks,the collaborative optimization of communication and sensing is realized,breaking through the bottleneck in the construction of UAV digital twin systems.Theoretical derivation and simulation verification show that,compared with the traditional multi-carrier scheme and single carrier scheme,the proposed hybrid carrier scheme reduces the bit error rate by approximately 0.8 orders of magnitude and 1.9 orders of magnitude at 14 dB signal-to-noise ratio(SNR),respectively,and exhibits more significant performance advantages in the medium and high SNR regions.关键词
