Adaptive Lattice Filter on STM32H7 Devices
Description
This application note and the accompanying evaluation package describe implementation of adaptive recursive least square Lattice filters on STM32H7 microcontrollers. Lattice filter serves for adaptive estimation of an acoustic channel. It can be used for active noice cancellation. In ultrasound based hand gesture GUI applications, the Lattice filter can be used as part of an electronic detector of presence of hand and improves quality of hand distance measurement by removing of acustic reflections from static distant objects.
