DEVICE FOR ENCODING AND DECODING USING SMALLER BLOCK OF SYMBOLS

摘要

A method of encoding user data into codevectors of an error correcting code, includes generating a first block of data symbols including user data symbols and dummy data symbols; encoding the first block using an ECC encoder to obtain a codeword comprising the first block of data symbols and a second block of parity symbols; and generating a codevector by selecting a user data portion of the user data symbols from the first block and a parity portion of the parity symbols from the second block. The sum of a number of the user data portion and a number of the parity portion is smaller than the sum of a number of the user data symbols and a number of the parity symbols of the second block.

1. A device for encoding an information word into a codeword, the device comprising:
an encoder configured to receive the information word and a matrix, the encoder being further configured to encode the information word comprising k information symbols using the matrix comprising k rows and n+k columns for output of an intermediate codeword having k+n symbols; and a codeword generator configured to receive the intermediate codeword and output the codeword by omitting a number of symbols of the intermediate codeword.
