Abstract:
1. A method that facilitates transmitting low-density parity-check (LDPC) encoded data, comprising: mapping a plurality of bits of a codeword to a plurality of nodes of a selected LDPC code; incrementing the number of nodes in the selected LDPC code; and transmitting one of the selected LDPC code and the incremented LDPC code as a hybrid automatic repeat-request (HARQ) transmission; wherein the incrementing includes at least one of (a) adding one or more explicit parity bits and associated constraint nodes to the selected LDPC code, and (b) adding one or more core degree 2 accumulate nodes to the selected LDPC code while splitting an existing constraint node into two constraint nodes, and choosing (a), or (b), or (a) and (b), based on a chosen incrementing scheme.
