Design for lifted ldpc codes having high parallelism, low error floor, and simple encoding principle |
| abstract |
A method of data encoding is disclosed. An encoder receives a set of information bits and performs an LDPC encoding operation on the set of information bits to produce a codeword based on a matched lifted LDPC code. The matched lifted LDPC code is based on a commutative lifting group and includes a number of parity bits and a submatrix to determine values of the parity bits. An order of the lifting group (Z) corresponds with a size of the lifting. The determinant of the submatrix is a polynomial of the form: g a + (g 0 +g L _)P, where g 0 is the identity element of the group, g 0 = 9 L n 2ˆk , and P is a n arbitrary non-zero element of a binary group ring associated to the lifting group. The matched lifted LDPC code may be based on quasi-cyclic lifting where the determinant of the submatrix is of the form x a +(1+x L )P(x), wherein P(x) has at least two terms and 2 k L=0 mod Z for a positive integer k. |
