Analysis of UWB -OFDM system for Vehicle to Infrastructure communication

Ultra wide band (UWB) is a candidate technology for future wireless communication especial for vehicle to vehicle and vehicle to infrastructure communication. It uses very short pulses, so that the spectrum of the emitted signals may spread over several GHz and data rates is very important. In this paper, a Vehicle-Infrastructure (V2I) communication system based on the UWB-OFDM (Multi-Band Orthogonal Frequency Division Modulation) technology is studied and analysed. In this application, two parameters are analysed the channels effect and the data rate. The performances of the proposed solution are evaluated in terms of Bit Error Rate (BER) and data rate in AWGN and Rayleigh channels. The results simulations show that the UWB-OFDM system gives a good result in terms of BER and it is necessary to adapt the data rate to the channel propagation environment.
