ABSTRACT: Higher spectral efficiency and fast synchronization can be achieved by using time domain synchronous OFDM (TDS-OFDM). But unfortunately, it suffers from low bit error rate performance in long delay spread channels and its performance loss over fast time-varying vehicular channel. This paper proposed TDS-OFDM as a strong candidate for vehicle-to-vehicle (V2V) communication using time reversal technique to solve its BER performance degradation. V2V wireless channel is characterized by high mobility and dynamic environment. The time reversal OFDM assist single input multi output communication through channel achieve a high bandwidth capacity. The proposed scheme is tested for V2V tap delay multipath channels and simulation results show that TDS-OFDM based on time reversal technique can provide significant bit error rate improvement
