- Abstract
- Vehicle to everything (V2X) communication supports vehicle to anything communication for vehicle safety and cooperative Intelligent Transport System in vehicular environments. IEEE 802.11p modem has been developed and applied for V2X communication system. V2X radio channel has multipath fast fading due to moving vehicles and surrounded road structure. We proposed a new DFCE-AD which combines DFCE and antenna diversity for OFDM reception and analyzed the performance improvement in multipath fading channel. Through computer simulation, SNR gain of DFCE-AD over DFCE for QPSK modulation is approximately 6혻dB at PER = 10%. In other word, PER of DFCE-AD is improved over that of DFCE by about 20% at SNR = 10혻dB. This result will be applied for the short sized packet and low order OFDM modulation in vehicular multipath fading channel.
