Fourier Transforms Using Conjugacy Constarints Over Subfields For Quasi Cyclic Ldpc Codes
Abstract
Quasi cyclic low density parity check codes are broadly used in many digital communication and storage systems. The operations of these encoders are done by using generator matrices. We focus on the QC-LDPC code matrices of dimension ( and the entries are elements of GF(where p divides r and hence GF( is the subfield of GF().To reduce the complexity of the encoder
