This application discloses a signal anti-interference method and an electronic device, and relates to the field of terminals. A system-on-chip (SoC) chip may obtain parameter information (for example, an amplitude of a radio frequency signal, a phase of the radio frequency signal, a waveform of the radio frequency signal and the like) of the radio frequency signal coupled on a mobile industry processor interface (MIPI) signal line. Based on the parameter information of the radio frequency signal, the SoC chip may generate a reverse signal of the radio frequency signal, where the reverse signal is the same as the radio frequency signal in amplitudes (which may also be referred to as amplitude values) and waveforms and opposite in phases. The SoC chip may superimpose the reverse signal with a signal transmitted by the MIPI signal line, to eliminate the radio frequency signal coupled on the MIPI signal line.

Signal anti-interference method and electronic device

This application provides a terminal device, including a noise suppression structure, where the noise suppression structure is disposed on the metal middle plate, the noise suppression structure includes a hollow region running through the first surface and the second surface, and the hollow region communicates with the first cavity, so that digital signal noise that uses the first cavity as a transmission medium has a propagation path in a direction toward the antenna, the propagation path passes through the hollow region, and the hollow region is used to suppress the digital signal noise transmitted through the propagation path, so as to prevent antenna operating performance from being affected by the digital signal noise.
