Encoding of QC-LDPC Codes of Rank Deficient Parity Matrix

Journal of Engineering, 2016
the encoding of long low density parity check (LDPC) codes presents a challenge compared to its decoding. The Quasi Cyclic (QC) LDPC codes offer the advantage for reducing the complexity for both encoding and decoding due to its QC structure.
