Abstract

It is proposed to apply DSRC (Dedicated Short Range Communication) using OFDM to roadside-vehicle communication systems as a means to overcome frequency selective fading, shadowing and high-speed hand-over difficulties. The symbol rate per subcarrier of DQPSK which is a transmission parameter of the OFDM system was optimised. The goal is to achieve BER (bit error rate) of less than 10 power -5 under the conditions of transmission rate 2.048 Mbps, carrier frequency 5.8GHz, vehicle speed 180km/h, simulcasting of several roadside transmitters, maximum delay of less than 1 microsecond and utilise forward error correction (FEC). The transmitter and receiver of the DQPSK-OFDM system was developed in the 5.8GHz band and the BER performance was measured to show that an OFDM system was applicable to roadside-vehicle communication systems.
