Abstract
A processing system configured to sense an input object in a sensing region of a sensing device including a transmitter module coupled to a first transmitter electrode and a second transmitter electrode and configured to simultaneously apply a first transmitter signal to the first transmitter electrode and a second transmitter signal to the second transmitter electrode, wherein the first transmitter signal is based on a first one of a plurality of distinct codes and the second transmitter signal is based on a second one of the plurality of distinct codes. The processing system also includes a receiver module including receiver circuitry coupled to a first receiver electrode and configured to receive a first resulting signal with the first receiver electrode, the first resulting signal comprising effects corresponding to the first and second transmitter signals and a noise component. The processing system is configured to determine an estimate of the noise component using a third one of the plurality of distinct codes which is not associated with a transmitter signal.
