| 摘要 |
The present invention relates to an encoder for error correction code encoding input data words (D) into codewords (Z1, Z2), comprising an encoder input (1451) for receiving input data words (D) each comprising a first number Kldpc of information symbols, an encoding means (1452) for encoding an input data word (D) into a codeword (Zl, Z2, Z3, Z4) such that a codeword comprises a basic codeword portion (B) including a data portion (D) and a basic parity portion (Pb) of a second number Nldpc - Kldpc of basic parity symbols, and an auxiliary codeword portion (A) including an auxiliary parity portion (Pa) of a third number MIR of auxiliary parity symbols, and an encoder output (1454) for outputting said codewords (Z1, Z2). |
