Abstract:
A method for estimating arrival time based on noise cancellation includes transmitting, with a transmit terminal, an ultra-wideband pulse sequence; performing power sampling on a received ultra-wideband signal; averaging a power sampling sequence; carrying out a calculation to obtain a noise mean vector; using a sum-of-rank method to obtain a rank of a power mean column vector; setting a decision threshold; and performing time-of-arrival (TOA) estimation.
