1. A method for determining time of arrival, applied to a signal receiving device in a wireless communication system, comprising:
receiving positioning signals having different fading values from a base station in the wireless communication system,
generating time of arrival correction information according to front edge information of theoretical autocorrelation waveforms of the 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.
