Abstract: An example disclosed system for locating a signal source includes a receiver; and a plurality of node devices, wherein the receiver includes processing circuitry configured to perform operations including generating signal timing information including one or more pulses corresponding to a correlation with one or more frequencies based on each of a plurality of wireless signal streams, each of the wireless signal streams including a signal of interest; applying times and one or more determined gains for the signal of interest to permit estimate of a phase of the received signal; obtaining, from a memory device that stores the wireless signal streams, symbols of the signal of interest based on window periods associated with the pulses; formatting the symbols; and determining time-of-arrival information based on the formatted symbols.
