Real-time and Accurate Acoustic Indoor Localization With a Smartphone
摘要：The requirement for specific indoor location is more and more pressing. However, traditional approaches can only achieve a low accuracy. In this paper, we put forward a new approach to evaluate the target position with the acoustical Linear Frequency Modulation Signal（LFM）. Comparing with other acoustical approaches, it is robust to noise, and most importantly it can realize a high accuracy and a good real-time performance. Besides that, several innovative location methods are also compared and verified to promote the real-time, accurate and robust performance.
