A delay-doppler impulse-based sensing and communication method

Abstract

The invention is related to a delay-doppler impulse-based sensing and communication method for narrowband joint sensing and communication (JSAC) orthogonal time frequency space (OTFS) system, such as automotive radar system, that can achieve high-resolution range- velocity profiles through impulse channel estimation
