A scheme for localizing a wireless user equipment (UE) device's relative position with respect to a spatial configuration (101, 201) based on audio signatures received via a multi-channel audio system, e.g., an audio system of a vehicle (106A-106D) or home entertainment system (204A-204D). The wireless UE device (500) is configured to capture the audio signatures received from a head unit (102, 202) that are placed in an out-of-hearing band of a captured signal. The wireless UE device (500) includes a persistent memory module (535) having program instructions for processing the captured signal including the out-of-band signatures, which may comprise either channel-specific pseudo-random noise (PN) sequences or single-frequency tones, in order to compute time delays or power levels associated with the speaker channels. A localization module (550) is configured to estimate the wireless UE device's relative position based on the time delays or power levels. |
