In this paper, we design a signal detector for OTFS modulation based on transform-domain maximal ratio combining (TD-MRC). The proposed scheme leverages the Doppler diversity and the circulant banded block diagonal structure of the effective channel matrix, which is computationally efficient compared to the traditional MRC detector due to its matrix-inversion-free nature. Another particularly appealing feature of TD-MRC is that its reliability performance improves as the maximal relative velocity increases. Numerous simulation results are presented to demonstrate the superior performance of the proposed method in comparison with the state-of-the-arts.
