Orthogonal time frequency space (OTFS) is a two-dimensional modulation scheme designed in the delay-Doppler domain, for combating the high mobility environment toward future wireless communications. In this paper, we propose a novel generalized spatial modulation combined OTFS (GSMOTFS) system, aiming at achieving better system performance compared to the conventional multiple-input multiple-output OTFS (MIMO-OTFS) and GSM orthogonal frequency division multiplexing (GSM-OFDM) systems. Furthermore, a decision feedback detector based on the minimum mean square error (MMSE) criterion is also developed toward efficient signal detection for the proposed GSM-OTFS system.
