N2 - In this paper, an orthogonal time frequency space (OTFS) system based on generalized spatial modulation (GSM) is proposed to overcome the high Doppler frequency shift in mobile communication scenarios. The proposed system fully takes the advantages of OTFS and GSM, and can achieve higher spectral efficiency and better bit error rate (BER) performance. The GSM based OTFS (GSM-OTFS) system and its signal processing have been presented first. Furthermore, the theoretical average BER of the GSM-OTFS system is derived with the union bound technique and the moment generating function (MGF). Numerical results show that the theoretical results of average BER performance of the GSM-OTFS scheme match well with the simulation results, which proves the correctness of our theoretical analysis, and the GSM-OTFS system can achieve better BER performance and spectral efficiency compared with the traditional spatial modulation based OTFS (SM-OTFS) system.
