INTERLEAVING METHOD BASED ON LDPC CODE, DEINTERLEAVING METHOD, INTERLEAVER, AND DEINTERLEAVER THEREOF

摘要

Interleaving method based on low density parity check (LDPC) code, comprises: dividing the check part of LDPC code as the unit with spread factor to get a plurality of check blocks; interleaving block-reciprocally the check blocks so as to make the check part of LDPC code be transferred to the interleaved check part; forming the output signals in accordance with the current information part of LDPC code and the interleaved check part, wherein said information part of LDPC code is before the interleaved check part. The corresponding interleaver, deinterleaving method, and deinterleaver are also disclosed. Deleting the check bits of LDPC code indirectly and continuously can be avoided.
