Realization of WAVE System Based on IEEE 802.11p

Abstract

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.
