Abstract
A method of determining a time of arrival (ToA) of a wireless transmission includes: sampling a signal received in a wireless transmission to generate first data in a time domain, performing a FFT on the first data to generate second data in a frequency domain, dividing the second data by a reference signal to obtain a channel frequency response, performing and IDFT on the channel frequency response to obtain a channel impulse response, determining a peak in the channel impulse response; and determining the ToA based on the peak.
