Executive Summary

Vehicle-To-Vehicle (V2V) communication systems will play an important role in Intelligent Transportation Systems (ITS). But in high mobility road condition, Orthogonal Frequency Division Multiplexing (OFDM) is very sensitive to Doppler shift. In this scenario Multiple Input and Multiple Output (MIMO) system combined with OFDM, make MIMO -OFDM techniques very attractive and productive for vehicle-to-vehicle communications. This paper deals with the Bit Error Rate (BER) performance analysis of MIMO-OFDM system in high way road condition which is modeled based on the Nakagami fading characteristic. The system performance is analyzed with the change in m value of Nakagami channel and also with the variation in the modulation schemes.
