LTE-V和DSRC共享频谱资源的研究

Spectrum Resources Sharing between LTE-V and DSRC

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。

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.
