“In the realm of high Doppler wireless scenarios, a novel modulation technique called OTFS has emerged. To address the parameter estimation challenge in OTFS-integrated radar and communication systems, a method leveraging sparse reconstruction preprocessing has been proposed. This approach, which reduces the computational load of the traditional WSF algorithm, involves constructing an OTFS echo signal model, transforming the signal to the time domain for initial coarse estimation, and then refining the estimate using the WSF algorithm. Simulations have confirmed the method's effectiveness and superiority.”
