Abstract
Official abstract text for this publication.
An encoder for error correction code encoding input data words (D) into codewords (Z 1 , Z 2 ) includes an encoder input for receiving input data words each including a first number K ldpc of information symbols, an encoding unit for encoding an input data word (D) into a codeword (Z 1 , Z 2 , Z 3 , Z 4 ) such that a codeword includes a basic codeword portion (B) including a data portion (D) and a basic parity portion (Pb) of a second number N ldpc - K ldpc 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 for outputting the codewords (Z 1 , Z 2 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. An encoder for error correction code encoding input data words (D) into codewords (Z 1 , Z 2 ), comprising: an encoder input configured to receive input data words (D) each comprising a first number K ldpc of information symbols, an encoder configured to encode an input data word (D) into a codeword (Z 1 , Z 2 , Z 3 Z 4 ) such that a codeword comprises a basic codeword portion (B) including a data portion (D) and a basic parity portion (Pb) of a se…
