Patent Searching and Data

Document Type and Number:
WIPO Patent Application WO/2019/026981
Kind Code:
An encoder for encoding source information into an encoded codeword used in a communication channel includes a data input to receive source data, a processor, and a memory to store an encoder program. The encoder program makes the processor to encode the source data into a turbo product coding (TPC) structure, and the TPC structure comprises a data block (90) corresponding to the source data, a first parity block (190) including a first column part (191), a first corner part (192) and a first bottom part (193), the first parity block being arranged so as to cover a right end column of the data block, a right bottom corner of the data block and a bottom row of the data block by the first column part, the first corner part and the first bottom part, and a second parity block (195) having a row parity block (196), a joint parity block (197) and a column parity block (198). The first parity block may be obtained by BCH encoding of the data block (outer encoding). This is followed by a (inner) turbo polar code generating the second parity block.
