Title:
DIFFERENTIAL SIGNAL COMPENSATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/177422
Kind Code:
A1
Abstract:
Provided are a differential signal compensation method and apparatus, which relate to the technical field of signal transmission. The method comprises: for each of two differential transmission lines, acquiring the attenuation coefficient of the differential transmission line to the signal amplitude of one test differential signal transmitted in the differential transmission line; acquiring a differential time delay factor, wherein the differential time delay factor is a time delay when two test differential signals arrive at a signal receiving end; and compensating, according to the differential time delay factor and each of the attenuation coefficients, the differential signal received by the signal receiving end. The present invention solves the problem in the prior art that two differential signals at a signal receiving end have a time delay, and achieves the effects of compensating a differential signal which has a time delay at a signal receiving end and further avoiding the time delay.
