Title:
FLATNESS COMPENSATION METHOD AND APPARATUS, AND STORAGE MEDIUM AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/028073
Kind Code:
A1
Abstract:
Disclosed in the present invention are a flatness compensation method and apparatus, and a storage medium and an electronic device. The method comprises: sampling, at an oversampling interval, a gain of a transceiver link in a frequency range affected by a baseband signal, so as to obtain a gain sequence; generating an offset sequence according to the gain sequence and a gain reference value, wherein the gain reference value is an expected flat link gain value; performing extraction on the offset sequence with an oversampling multiple corresponding to the oversampling interval, so as to obtain an initial correction sequence; optimizing the initial correction sequence to obtain an optimized correction sequence; converting the optimized correction sequence to obtain a filter tap coefficient; and generating a target filter according to the filter tap coefficient, and using the target filter to compensate for the baseband signal. By means of the technical solution, the problem in the related art of the compensation effect of a filter generated by means of a conventional IFFT or training method pre-compensating for a baseband signal being poor is solved.
