LDPC DESIGN FOR HIGH PARALLELISM, LOW ERROR FLOOR, AND SIMPLE ENCODING |
摘要 |
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. A determinant of the submatrix is a polynomial of the form: ga+(g0+gL)P, where g0 is the identity element of the group, g0=gL2k, and P is an arbitrary non-zero element of a binary group ring associated to the lifting group. |

1. A method of data encoding, the method comprising:
receiving a set of information bits; performing a low density parity check (LDPC) encoding operation on the set of information bits to produce a codeword based on a matched lifted LDPC code, wherein the matched lifting is based on a commutative lifting group and wherein the LDPC code includes a number of parity bits and a submatrix to determine values of the parity bits, and wherein:
an order of the lifting group (Z) corresponds with a size of the lifting;a determinant of the submatrix is a polynomial of the form: ga+(g0+gL)P, wherein:
g0 is the identity element of the group,g0=gL2k, andP is an arbitrary non-zero element of a binary group ring associated to the lifting group. |
