DCOC calibration method and device and storage medium

The invention relates to a DCOC calibration method and device and a storage medium. The DCOC calibration method comprises the following steps: when the output polarity of a preset branch is a first preset value and the in-phase end register configuration value and the anti-phase end register configuration value are both first preset configuration values, obtaining a corresponding first register residual parameter; when the output polarity of the preset branch is a first preset value and the in-phase end register configuration value and the anti-phase end register configuration value are both second preset configuration values, obtaining a corresponding second register residual parameter; and determining a preset calibration rule according to the first register residual parameter and the second register residual parameter, and performing DCOC calibration by using the preset calibration rule. By using the DCOC calibration method provided by the invention, the DC offset cancellation can be completed in an extrem
