英文摘要	Spatial modulation orthogonal frequency division multiplexing (SM-OFDM) is a novel OFDM technique which conveys additional information by active antenna indices of subcarriers, and thus achieves enhanced data rate and robustness against inter-antenna interference within subcarriers. Index modulated OFDM (IM-OFDM) applies the concept of index modulation to subcarrier domain and is shown to have reduced inter-carrier interference (ICI). In this paper, we propose SM-OFDM with subcarrier index modulation (ISM-OFDM) for vehicle-to-vehicle and vehicle-to-infrastructure (V2X) to mitigate the ICI caused by Doppler effects. The idea is to to embed subcarrier index modulation to SM-OFDM and conduct SM at the active subcarriers independently. It is shown via computer simulations that the proposed scheme achieves better bit error rate (BER) performance than classical SM-OFDM systems under V2X channel models. ? 2016 IEEE.; EI
