Title:
MEHOD AND DEVICE FOR ADAPTIVE DECISION FEEDBACK EQUALIZATION, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/120615
Kind Code:
A1
Abstract:
Disclosed is a method for adaptive decision feedback equalization, comprising: a feedforward equalizer performing a filtering processing of an inputted first signal, according to a finite impulse response filtering strategy, to obtain a first filtering result, and outputting the first filtering result to a determiner; after the determiner outputs a second signal, a feedback equalizer receiving the second signal, and performing a filtering processing of the second signal, according to the finite impulse response filtering strategy, to obtain a second filtering result; and performing a filtering processing of the second signal, according to an infinite impulse response filtering strategy, to obtain a third filtering result; obtaining the difference between the third filtering result and the second filtering result as the first difference; the determiner receiving a third signal which is obtained according to the sum of the first filtering result and the first difference, and obtaining, according to the third signal, the second signal associated with the third signal; the second signal being the known transmission level closest to the third signal. Further disclosed are a device for adaptive decision feedback equalization, and a computer storage medium.
