Abstract

Intelligent transportation system is a prominent technology solution for the vehicle manufacturers in this present scenario. The manufacturers are trying to deploy an advanced system for automation through sensing. Various technologies are being used to communicate with other near-by vehicle and to sense their perspective on the road. The important problem is to share the radar and communication information with other vehicles without any time delay. The vehicles uses a different hardware system for establishing radar sensing and communication concurrently, which increases the cost and bandwidth requirement of the overall system. Instead of using multiple system and hardware separately for communication and remote sensing, a single hybrid system might be a cost effective solution which will serve both communication and remote sensing requirements. This work proposes a concept for integrating radar sensing and hybrid communication system (IRSHCS) with multiple input multiple output (MIMO) orthogonal frequency division multiplexing (OFDM) in a single hardware known as software defined radio. It serves simultaneous remote sensing and communication to the vehicle user without delay with the dedicated short range communication system and worldwide interoperability for microwave access. Moreover, an optimization problem is formulated to improve the performance of IRSHCS, which focuses on sharing both the radar and communication between the vehicles without any time delay by satisfying the radar and communication system requirements with suitable parameters. The whale optimization algorithm generates an optimal solution to solve the limitations of the hybrid system by choosing maximum channel capacity as its objective function. Experimental results are evaluated to demonstrate the IRSHCS MIMO OFDM system provide better performance as compared to the conventional approaches.

混合通信与遥感在ITS应用中的集成

摘要

在当前情况下，智能交通系统是车辆制造商的一项重要技术解决方案。制造商正在尝试部署用于通过感测实现自动化的高级系统。正在使用各种技术与其他附近的车辆通信并感知其在道路上的视野。重要的问题是在没有任何时间延迟的情况下与其他车辆共享雷达和通信信息。车辆使用不同的硬件系统来同时建立雷达感测和通信，这增加了整个系统的成本和带宽要求。与其将多个系统和硬件分别用于通信和遥感，不如使用单个混合系统可能是一种经济高效的解决方案，它将满足通信和遥感的需求。这项工作提出了将雷达感测和混合通信系统（IRSHCS）与多输入多输出（MIMO）正交频分复用（OFDM）集成在称为软件定义无线电的单个硬件中的概念。它通过专用的短距离通信系统以及微波访问的全球互用性，为车辆用户提供了同时进行的遥感和通信，而不会出现延迟。此外，提出了一个优化问题以提高IRSHCS的性能，该优化问题的重点是通过以合适的参数满足雷达和通信系统的要求，在没有任何时间延迟的情况下共享雷达和车辆之间的通信。鲸鱼优化算法通过选择最大通道容量作为其目标函数，从而生成最佳解决方案来解决混合系统的局限性。对实验结果进行了评估，以证明IRSHCS MIMO OFDM系统与传统方法相比具有更好的性能。
