Electronic device and method for removing interferential signals of mobile device

A non-transitory storage medium storing a set of instructions, the set of instructions being executed by a processor of an electronic device, to perform a method comprising:

• (a) acquiring an original communication signal waveform formed by communication signals of a mobile device near the electronic device, and acquiring multiple signal frames from the original communication signal waveform;
• (b) calculating a differential signal of each signal frame in a group, to generate a corresponding differential signal waveform, and acquire a differential positive pulse peak value (DPPPV) of the differential signal waveform;
• (c) calculating a differential threshold value (DTV) according to the DPPPV corresponding to the signal frames in the group;
• (d) determining the differential signal of a signal frame in the group to be an interferential signal, in response to that the DPPPV corresponding to the signal frame is not less than the DTV, there is a differential negative pulse peak value (DNPPV) at a target time point of the differential signal waveform, and the DNPPV is not less than a second preset ratio of the DPPPV;
• (e) determining a signal interference section based on positions of wave troughs of the DPPPV and the DNPPV;
