| 17. A method for decoding EC-encoded data generated by (1) applying an outer EC encoder to a first block of data to generate
a first block of symbols and (2) applying at least one inner EC encoder to the first block of symbols to generate a first
block of codewords, the method comprising:
(a) applying at least one inner EC decoder to decode a second block of codewords corresponding to the first block of codewords,
which decoding of the second block of codewords generates a second block of symbols corresponding to the first block of symbols,
wherein the inner EC decoder independently decodes each codeword in the second block of codewords, at least one codeword being
decoded by the inner EC decoder to generate two or more symbols in the second block of symbols; and
(b) applying an algebraic outer EC decoder to the second block of symbols to generate a second block of data corresponding
to the first block of data, wherein:
the at least one inner EC decoder comprises a two-dimensional product code (2DPC) decoder; and
the algebraic outer EC decoder is an algebraic array decoder.
