Abstract:
A family of quasi cyclic irregular low density parity check codes for video broadcasting applications. The parity check matrices of the constructed low density parity check codes have quasi-cyclic structures to facilitate hardware implementation and have proper check/bit degree distributions to offer frame error rate performance lower than 10−7.
