SLIDING BLOCK DECISION EQUALIZER
Document Type and Number:
WIPO Patent Application WO/2022/001862
Kind Code:
A1
Abstract:
A method and apparatus for signal equalization are provided. Multiple decision components are arranged in a sequence, beginning with a history portion and ending with a decode portion. Each decision component performs a decode decision on a symbol. Decode decisions are passed forward to other decision components where they can be used to compensate for intersymbol interference. Decode decision output by the history portion are otherwise discarded, while decode decisions output by the decode portion are output as a decoded signal. In the next decode cycle, input previously provided to the decode portion is again provided to the history portion, in a sliding, overlapping block manner.
