Title:
CHANNEL DECODING METHOD AND APPARATUS USING STRUCTURED PRIORI INFORMATION OF PREAMBLE
Document Type and Number:
WIPO Patent Application WO/2017/213409
Kind Code:
A1
Abstract:
A channel decoding method is provided. The method includes storing, in a memory, a set of first log likelihood ratio (LLR) values corresponding to bits of a codeword generated by modulation of a channel-encoded signal; changing, into a preset value, at least one LLR value corresponding to previously defined bits of the codeword from among the set of the first LLR values, to generate a set of second LLR values; and performing forward error correction (FEC) based on the set of the second LLR values and an FEC code, to estimate the bits of the codeword, in which the FEC code comprises a constraint code for constricting a previously defined structural correlation between the bits of the codeword.
