  • Ultra-wideband pulse and ultra-wideband pulse-based ranging
    Patent number: 12553998
    Abstract: A method for generating an ultra-wideband signal is provided. The method comprises the steps of generating at least one ultra-wideband pulse envelope comprising a main pulse and a precursor pulse, the precursor pulse being shorter in length and lower in amplitude compared to the main pulse, and modulating a carrier signal in amplitude such that the envelope corresponds to the at least one ultra-wideband pulse envelope and such that the carrier signal within the main pulse is phase-shifted with respect to the carrier signal within the precursor pulse.
