Abstract :
In this paper, we introduce the cooperative diversity (CD) into the vehicle to vehicle (V2V) communications. As the fast changes and the multi-path fading of the channel between V2V, the differential detection (DD) and OFDM (orthogonal frequency division multiplexing) is used to bypass the channel estimation and decrease the effect of the multi-path fading. As the theoretic and simulation show: The DD-OFDM-CD can improve the performance of V2V in fast changing multi-path fading channel
