Abstract
The disclosure relates to a mobile device, comprising: a radio receiver configured to receive a radio signal; a power receiving unit (PRU) configured to receive a wireless charging signal from a power transmission unit (PTU) configured to charge the mobile device; a wireless broadcast receiver configured to receive a harmonic of the wireless charging signal during charging of the mobile device; a frequency manager configured to scan for a frequency of the harmonic and to detect a fundamental frequency of the wireless charging signal based on the scanned harmonic; and a mitigation module configured to mitigate a harmonic content of the wireless charging signal in the received radio signal based on the detected fundamental frequency of the wireless charging signal.
