1. A method comprising:
- receiving, by a processor of a mobile device, one or more signals from one or more inertial sensors on said mobile device;
receiving, by the processor, a received power signal from a distance sensor on said mobile device;
determining, by the processor, a DC offset component of said received power signal based, at least in part, on said one or more signals received from said one or more inertial sensors; and
calibrating, by the processor, the distance sensor based on the determined DC offset.
