Quasi-cyclic (QC) low-density parity-check (LDPC) codes which are known as QC-LDPC codes, have many applications due to their simple encoding implementation by the means of cyclic shift registers. In ...

This paper uses tools from matrix algebra over commutative rings to simplify the design of parity-check (PC) matrices for Quasi-cyclic (QC) low-density parity-check (LDPC) codes. These tools are also ...
