Title:
A CHANNEL CODING, MODULATING AND MAPPING METHOD FOR HYBRID AUTOMATIC REPEAT REQUEST OF LOW DENSITY PARITY CHECK CODE
Document Type and Number:
WIPO Patent Application WO/2008/151498
Kind Code:
A1
Abstract:
A channel coding, modulating and mapping method for hybrid automatic repeat
request of low density parity check code is disclosed. The method comprises following
steps: structured LDPC coding K bits information input by the channel coder,
sending the generated code to the HARQ buffer; rearranging the bits of the LDPC
HARQ mother code codeword, selecting bits of the codeword sequentially, generating
binary sequence of HARQ packet; mapping the codeword bits of the HARQ packet to
the constellation to make sure that high-order bits are mapped to the high reliability
bits. The method provides the max gain of the constellation for the LDPC codeword,
and also provides the best performance of the LDPC HARQ channel coding.
