Inter-carrier interference (ICI) in vehicle to vehicle (V2V) orthogonal frequency division multiplexing (OFDM) systems is a common problem that makes the process of detecting data a demanding task. Mitigation of the ICI in V2V systems has been addres

This paper proposes a novel scheme to transmit signals in a downlink multiuser multiple input-multiple output scenario. The proposed scheme combines spatial shift keying modulation and orthogonal Walsh codes. Analytical and simulation results show th
