Abstract

A processing system for reducing interference. The processing system includes: a sensor module configured to: receive a noisy active pen signal associated with an active pen from a panel receiver; and receive a plurality of interference signals from a plurality of interference receivers; and a determination module configured to: determine an estimated interference signal based on a subset of the plurality of interference signals; and generate a filtered active pen signal by reducing interference in the noisy active pen signal based on the estimated interference signal.
