In a method for removing interferential signals of a mobile device, a differential signal waveform corresponding to a signal frame of an original communication signal waveform of the mobile device is generated, and a DPPPV of the differential signal waveform is acquired. The differential signal is determined to be an interferential signal, in response to that the DPPPV is not less than a preset differential threshold value, and a DNPPV at a target time point is not less than a preset ratio of the DPPPV. A signal interference section is determined and compensation values corresponding to the signal interference section is calculated, to generate a differential compensation waveform of the signal frame. An integrated differential compensation waveform of all signal frames and the original communication signal waveform are incorporated to obtain a processed signal waveform without interferential signals. |
