Doppler Shift Mitigation in Acoustic Positioning Based on Relative Speed of Base Station for Smartphones

To mitigate the tracking error of moving targets caused by the Doppler shift in acoustic indoor positioning system (AIPS), a novel mitigation method is proposed in this article. It first uses the audio arrival times (AATs) of two adjacent positioning cycles to estimate the relative speed of base sta...
