Abstract
Method and system method performed at a wireless transmitting station, including generating a first low density parity check (LPDC) codeword for a first source word for a first transmission, and generating a second LDPC codeword for a retransmission for the first LDPC codeword, the second LDPC codeword including a permutated subset of information bits included in the first LDPC codeword and parity check bits corresponding to the permutated subset of information bits.
