Encoding low density parity check (LDPC) codes through an LPDC decoder

摘要

An approach is providing for supporting broadcast transmission of low density parity check (LDPC) coded signals. A receiver includes a decoder (101) configured to decode an LDPC signal to output a decoded signal. The decoder (101) is further configured to operate as an encoder; as such, interference cancellation can be implemented by the encoder re-encoded the received decoded signal. The above approach has particular applicability to satellite broadcast systems.
