Document Type and Number:
WIPO Patent Application WO/2016/115996
Kind Code:
A1
Abstract:
Disclosed are a non-linear compensation method and device. The method comprises: calculating an actual ratio of an outer ring radius to an inner ring radius of a constellation diagram in a 16 quadrature amplitude modulation (16QAM) system at a current moment; feeding back output adjustment information to a digital analog converter (DAC) according to a relationship between the actual ratio of the outer ring radius to the inner ring radius and an ideal ratio of the outer ring radius to the inner ring radius, to instruct the DAC to adjust an output voltage ratio; and repeating the foregoing steps until the relationship between the actual ratio of the outer ring radius to the inner ring radius and the ideal ratio of the outer ring radius to the inner ring radius reaches an expected ratio.
