Abstract: Disclosed are a method and an apparatus for determining time of arrival, a signal receiving device, and a non-transitory computer readable storage medium. The method for determining time of arrival includes: generating time of arrival correction information according to front edge information of theoretical autocorrelation waveforms of positioning signals having different fading values; calculating a front edge slope corresponding to a front edge reference point of a correlation waveform of an actually received signal; and determining target correction information from the time of arrival correction information according to the front edge slope, and determining the time of arrival of the actually received signal based on the target correction information.

Abstract: A method and device for determining a time of arrival (TOA), a terminal device, and a non-transitory computer-readable storage medium are disclosed. The method may include: determining a detection start time on a correlation waveform based on a leading edge detection threshold; determining a noise threshold on the correlation waveform, and determining a quasi-TOA according to the detection start time; and determining the TOA according to data information in a target area of the correlation waveform and the noise threshold, where the target area is determined based on the quasi-TOA and a detection length.
