LTE-V和DSRC共享频谱资源的研究

[摘要] 提出了一种专用短程通信技术（DSRC）与基于长期演进（LTE）的车对外界信息交互技术（LTE-V）共享频谱资源的机制，该机制从物理层和数据链路层2方面对DSRC技术和LTE-V技术进行了改进。通过仿真验证了该机制能够有效地减小DSRC与LTE-V系统间的干扰，并且能够使LTE-V设备在一定条件下接收DSRC信号，从而提高了采用LTE-V设备的车辆感知周围车辆的能力。

[Abstract] In this paper, a mechanism for dedicated short range communications (DSRC) and long term evolution (LTE)-based vehicle-to-external information exchange (LTE-V) to share the spectrum resources is proposed. This mechanism improves the DSRC technology and LTE-V technology on physical layer and data link layer. And the simulation results show that the proposed mechanism can effectively reduce the interference between DSRC system and LTE-V system, and allow the LTE-V based devices to receive the DSRC signal under certain conditions, thus improving the ability of vehicles using LTE-V based devices to perceive the surrounding vehicles.
