Measuring Time-of-Flight in an Ultrasonic LPS System Using Generalized Cross-Correlation

Measuring Time-of-Flight in an Ultrasonic LPS System Using Generalized Cross-Correlation

In this article, a time-of-flight detection technique in the frequency domain is described for an ultrasonic Local Positioning System (LPS) based on encoded beacons. Beacon transmissions have been synchronized and become simultaneous by means of the DS-CDMA (Direct-Sequence Code Division Multiple Ac...
