V2V通信中基于检测放大转发的高可靠通感一体化空间调制
Highly Reliable Integrated Sensing and Communication Spatial Modulation Based on Detected Amplify and Forward in V2V Communication
摘要
Abstract
In Vehicular Ad Hoc Network(VANET),the long-distance and obstacles between vehicles are the main factors of de-creasing reliability in Vehicle to Vehicle(V2V)communication.This paper proposes a high-reliability Integrated Sensing and Commu-nication(ISAC)combined with Spatial Modulation(SM)and based on Detected Amplify and Forward(DAF)algorithm.The algorithm utilizes the radar detection capability of ISAC to select the vehicle with the highest Signal to Noise Ratio(SNR)as relay vehicle,ai-ming to transmit information from the source vehicle to the target vehicle.At relay vehicles,noise accumulation is eliminated through DAF,thereby enhancing reliability.On this basis,SM is introduced,utilizing the sparsity of the transmitted signals to reduce adjacent-channel interference and further improve reliability.The Outage Probability(OP)was derived.And simulations were conducted to vali-date the impact of transmit power on OP under different hop counts.Its complexity and latency are analyzed.The results indicate that under various scenarios,the algorithm effectively enhances the reliability of V2V communication within a certain level of complexity.This study provides theoretical support for low-latency and high-reliability under long-distance transmission of V2V communication in VANET.关键词
