A polarisation coding scheme based on an integrated sensing and communication system

Abstract

Integrated sensing and communication (ISAC) technology enhances the spectrum utilization of the system by interchanging the spectrum between communication and sensing, which has gained popularity in scenarios such as vehicle-to-everything (V2X). With the aim of providing more dependable services for vehicles in high-speed mobile scenarios, we propose a scheme based on sense-assisted polarisation coding. Specifically, the base station acquires the vehicle's positional information and channel strength parameters through the forward time slot echo information. This information informs the creation of the coding architecture for the following time slot. This approach not only optimizes resource consumption but also enhances system dependability. Our simulation results confirm that the introduced scheme displays a notable improvement in the bit error rate (BER) when compared to traditional communication frameworks, maintaining this advantage across both unimpeded and compromised channel conditions.
