Abstract
Disclosed herein is a concatenated code encoding method for improving a turbo code. The concatenated code encoding method of the present disclosure includes encoding an input signal based on a repetition-accumulation (RA) code as an outer code, adding a tail bit to the encoded input signal, and encoding the encoded input signal based on the a turbo code. The concatenated code encoding method may further include interleaving the encoded input signal after application of the outer code.
Claims8
A method of encoding a concatenated code, comprising:
- generating a first codeword from an input signal using a repetition-accumulation (RA) code as an outer code;
- adding a tail bit to the first codeword;
- and
- generating a second codeword from the first codeword with the added tail bit using a turbo code as an inner code,
- wherein the generated first codeword comprises a plurality of regions,
- wherein each of the regions contains the input signal,
- wherein the tail bit is added to the last one of the regions.
A method of decoding a concatenated code, comprising:
- decoding a first codeword from a second codeword based on a turbo code, using a tail bit contained in the second codeword;
- and
- decoding an input signal from the first codeword based on a repetition-accumulation (RA) code,
- wherein the first codeword comprises a plurality of regions,
- wherein each of the regions contains the input signal,
- wherein the tail bit is added to the last one of the regions.
