Pre-equalization compensation method and device for link, storage medium and electronic device

A pre-equalization compensation device for a link, comprising:

• a parsing unit configured to, in response to that an AAU is powered on, parse a prestored off-line compensation table to obtain first non-flatness equalization coefficients of an RF link with a plurality of sub-carriers and second non-flatness equalization coefficients of a wave control link with the plurality of sub-carriers, wherein each one of the plurality of sub-carriers is corresponding to one of the first non-flatness equalization coefficients and one of the second non-flatness equalization coefficients;
• a combining unit configured to combine the first non-flatness equalization coefficients of the plurality of sub-carriers and the second non-flatness equalization coefficients of the plurality of sub-carriers to obtain a combined carrier non-flatness coefficient;
• and
• a processing unit configured to perform equalization compensation on the link according to the combined carrier non-flatness coefficient, wherein the equalization compensation is used for improving signal flatness in the whole link,
• wherein the first non-flatness equalization coefficients of the Radio Frequency (RF) link comprise flatness characteristic parameters of a downlink data link, the second non-flatness equalization coefficients of a wave control link comprise flatness characteristic parameters of an antenna panel.
