首先根据IEEE 802.11p 协议建立了一个系统仿真模型,其次具体描述了系统设计中的关键技术,包括OFDM系统参数带宽速率选择、导频子载波设计、同步与估计算法设计等,通过系统仿真模型发现存在的问题,并调研和改进信道估计算法,以适应移动场景下的不利因素。在FPGA平台上进行了具体的实现,评估硬件平台下的处理速度、容量及处理性能。最后,在实际车路场景下演示移动车辆通过原型系统对路灯进行控制。
A simulation system and hardware platform based on IEEE 802.11p proposal was established. Then
key technologies of system design include OFDM parameter bandwidth and data rate choice
pilots' structure design
synchronization and channel estimation design
were presented. A novel channel estimation method to eliminate the disadvantage in vehicle environment was proposed. The vehicle communication system based on IEEE 802.11p was realized on FPGA hardware platform. The processing speed
storage and performance on the platform were appraised
and then a demo about the vehicle control traffic light in vehicle-to-roadside environment on the platform was realized.
