A frame covers a period of time, and locationing pulses are emitted once per frame. The pulses are detected by a mobile unit with a microphone, which is able to trilaterate its physical position. To counteract false positives from reverberations of pulses emitted in prior frames, a noise threshold function declines over the course of the frame. As such, small amplitude locationing pulses received late in a frame are still detected because the small amplitude pulse exceeds the decayed noise threshold function. In this way, the noise threshold function is a filter that may detect high amplitude pulses early in a frame as well as small amplitude pulses late in a frame without detecting reverberation pulses early in a frame as false positives."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Frame aware automatic gain control","description":"A method and apparatus for automatic gain control in a frame-aware pulsed ranging system is disclosed.
