1. A method comprising:
receiving, with a first electrode of a first device, a first signal comprising a signal component, the first device being operable to communicate wirelessly with a second device via the first electrode and through a sensor of the second device;
receiving a second signal from a second electrode of the first device, the second signal comprising a signal component, the first signal and second signal each containing noise having similar characteristics, and wherein the signal component of the first signal is a first version of a signal of the second device and the signal component of the second signal is a second version of the signal of the second device;
removing noise from the first signal by subtracting the second signal from the first signal, including generating an output that is the difference between the first signal and the second signal; and
determining the signal component of the first signal based on the output and the signal component of the second signal.
