MOBILE DEVICE LOCALIZATION USING AUDIO SIGNALS

摘要

Mobile device localization using audio signals is described. In an example, a mobile device is localized by receiving a first audio signal captured by a microphone located at the mobile device and a second audio signal captured from a further microphone. A correlation value between the first audio signal and second audio signal is computed, and this is used to determine whether the mobile device is in proximity to the further microphone. In one example, the mobile device can receive the audio signals from the further microphone and calculate the correlation value. In another example, a server can receive the audio signals from the mobile device and the further microphone and calculate the correlation value. In examples, the further microphone can be a fixed microphone at a predetermined location, or the further microphone can be a microphone located in another mobile device.

1. A computer-implemented method of localizing a mobile device, comprising:
receiving, at a processor, a first audio signal captured by a microphone located at the mobile device; receiving, at the processor, a second audio signal captured from a second microphone; and determining whether the mobile device is in proximity to the second microphone based on the first audio signal and second audio signal
