Abstract
A device for decoding a generalized concatenated code (GCC) codeword includes: a buffer; and at least one processor configured to: obtain the GCC codeword, calculate a plurality of inner syndromes based on a plurality of frames; calculate a plurality of sets of delta syndromes based on the frames; determine a plurality of outer syndromes based on the sets of delta syndromes; store the inner syndromes and the outer syndromes in a buffer; perform inner decoding on the frames based on the inner syndromes stored in the buffer; update at least one outer syndrome stored in the buffer based on a result of the inner decoding; perform outer decoding on the frames based on the updated at least one outer syndrome; and obtain decoded information bits corresponding to the GCC codeword based on a result of the inner decoding and the result of the outer decoding.
