In this paper, we propose a design methodology of low-density parity check (LDPC) code for very high speed transmission. To support various code rates with reasonable hardware and, possibly, the type-II hybrid automatic repeat request (HARQ), a row-splitting/combining method is employed in conjunction with shortening. In row-splitting approach, a parity check matrix of a high rate mother LDPC code,...
In this paper, we propose a design methodology of low-density parity check (LDPC) code for very high speed wireless transmission. To support various code rates with reasonable hardware a row-splitting/combining method is employed in conjunction with shortening. In row-splitting approach, a parity check matrix of a high rate mother LDPC code, saying rate 4/5, is designed first and then successively...
Previously, there has been no report on implementation effort to integrate LDPC encoder and decoder into a single hardware. In this paper, we propose a simple yet low complex systematic LDPC encoding method for class of quasi-cyclic low-density parity-check (QC-LDPC) codes to let LDPC encoder acquire an interchangeable structure, exploited in the decoder. With the proposed encoding scheme, implementation...
