Encoding and decoding methods and systems

摘要

An encoder for use in information processing applications includes an input configured to provide information bits to be encoded and a feedforward convolutional outer code encoder configured to encode the information bits to generate encoded information bits including the information bits and parity bits. The encoder may also include at least one interleaver configured to interleave the encoded information bits to generate an outer codeword. Further, the encoder may include a rate-1 1/(1+D) accumulate code based inner code encoder configured to encode the outer codeword to generate one or more codewords corresponding to the information bits.
