Abstract:
A method and system for the estimation and correction of the multipath delay is described. The method comprising analyzing the distortion of the autocorrelation function of each single impulse received with that of an ideal impulse, deriving back the variation of the impulse parameters and estimating the effect of the multipart to be taken into account for compensation on the estimation of the time of arrival (TOA) of the electromagnetic signal.
