An Ultrasonic Multiple-Access Ranging Core Based on Frequency Shift Keying Towards Indoor Localization
This paper describes a new approach and implementation methodology for indoor ranging based on the time difference of arrival using code division multiple access with ultrasound signals. A novel implementation based on a field programmable gate array using finite impulse response filters and an opti...
