Construction of QC LDPC Cycle Codes Over GF( ) Based on Cycle Entropy and Applications on Patterned Media Storage

In this paper, we focus on the construction of a type of quasi-cyclic low-density-parity-check (QC LDPC) codes called cycle codes. Based on our previous work, the maximum cycle entropy (MCE) algorithm for constructing nonbinary LDPC codes can be extended to its QC form (QC-MCE), which maintains the...
