Abstract
The present disclosure belongs to the technical field of acoustic positioning, and discloses an acoustic positioning system and method for a smartphone and a wearable device, and a terminal. A ranging signal is transmitted by virtue of a base station network, and specific space signals of which the frequencies are 12 kHz to 21 kHz are designed; the ranging signal is received and decoded by virtue of a user terminal, distances from base stations to the user terminal are estimated according to the first arrival signals, and the position of a user is estimated according to a plurality of distances measured on the position of the user. The present disclosure provides the acoustic positioning system (APS) for the smartphone and the wearable device, which is a technology for precise ranging based on acoustic waves.
