逆反射光通感一体化系统研究进展
Research progress on retroreflective optical integrated sensing and communication system
摘要
Abstract
To break through the bandwidth bottleneck of radio-frequency integrated sensing and communication(ISAC)sys-tems and improve the transmission distance and sensing accuracy of optical wireless communication,this paper systematically investigates the retroreflective optical integrated sensing and communication(RO-ISAC)system,focusing on its channel mod-eling,waveform design,and bidirectional transmission.By establishing sensing channel models for both point light sources and surface light sources,various integrated sensing and communication waveforms are designed,including pulse sequence sensing-pulse position modulation(PSS-PPM),fused pulse amplitude modulation(PAM),and clipped orthogonal frequency di-vision multiplexing(OFDM).Additionally,bidirectional transmission schemes based on time-division duplex and wavelength-division duplex are proposed to mitigate interference.The results demonstrate that the RO-ISAC system can achieve high-precision sensing and high-capacity communication in various typical scenarios such as indoor environments,unmanned aerial vehicles,and underwater applications,showing promising potential for practical deployment.关键词
