A novel optimized partial band preamble is designed and the corresponding filtering processing of received signal and the timing synchronization algorithm are also proposed for orthogonal time frequency space (OTFS) systems in high mobility scenarios. To optimize timing synchronization performance, the occupied bandwidth of the preamble is formulated as an optimization problem and solved via the offline exhaustive search. Simulation results show that, compared with the available best performance benchmark algorithm, the proposed method achieves a 2dB signal-to-noise ratio gain under the same capture probability, and its root mean square error of timing offset estimation is only 1/3 that of the available benchmark algorithm.
