Communication in high speed railway (HSR) is a critical issue which could be used for traffic control and guarantee safety. Unfortunately, channel condition of HSR communication is extremely time-varying due to large Doppler effect from high mobility and fast environments alternating. In this paper, spatial modulation is introduced to HSR communication as a multi-antenna candidate technique for its many advantages. It indicates that high spectral efficiency and good robustness can be achieved by using spatial modulation in HSR communication. Then, we further provide some potential application scenarios for HSR communication system. Numerical results show that spatial modulation with proper receivers outperforms V-BLAST or space-time coding in certain cases. Furthermore, the results validate the potential of spatial modulation applying to HSR communication.
