Title:
DISTRIBUTION MATCHING CIRCUIT, DISTRIBUTION MATCHING TERMINATION CIRCUIT, DISTRIBUTION MATCHING METHOD, DISTRIBUTION MATCHING TERMINATION METHOD AND OPTICAL TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/031257
Kind Code:
A1
Abstract:
In a distribution matching circuit (1),a plurality of items of LUT output data hierarchized in a tree structure sequentially specify a combination of signal point groups in a signal space managed by an LUT at an immediately subordinate tier, and signal point information after distribution matching is output for each of the LUTs at the lowest tier.
