The present disclosure describes systems and methods for time-of-arrival (TOA) estimation techniques. Some embodiments of the disclosure provide for estimating radio propagation path parameters based on a training signal received over a set of active frequencies. The radio propagation path parameters (e.g., fading coefficients for each path) are used to reconstruct a channel frequency response on null frequencies (e.g., frequencies that did not include or carry the received training signal). A time-of-arrival parameter can then be estimated based on the estimated channel frequency response and the reconstructed channel frequency response (e.g., the channel frequency response estimated using both active frequencies and null frequencies).
A method comprising:
An apparatus comprising a processor and a memory storing instructions and in electronic communication with the processor, the processor being configured to execute the instructions to:
A non-transitory computer readable medium storing code for time-of-arrival estimation techniques, the code comprising instructions executable by a processor to:
