Pulse interference suppression method, suppression system, equipment and chip

The invention relates to the field of communication, and discloses a pulse interference suppression method and system, equipment and a chip. The suppression method comprises the following steps: determining the sum of power in each sub-window on a plurality of levels divided by an observation window, wherein the length of each sub-window is greater than or equal to the pulse width; according to the total length of the observation window and the power sum in each sub-window on each hierarchy, determining the average power in effective sub-windows meeting a preset condition on a specific hierarchy and the length of each sub-window; adjusting the data frame according to the average power and the target analog gain in the effective sub-window; and adjusting the data frame subjected to analog gain adjustment according to sampling data within a window length for digital gain control before the current moment and a target digital gain, the window length being greater than the length of each sub-window on a specific
