  • Family of LDPC codes for video broadcasting applications
    Patent number: 8689092
    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.
    Type: Grant
