N2 - The multifold turbo coding, designed to provide multiple extrinsic estimates and LLRs on a bit basis during decoding iterations, is introduced. Component encoders accept various combinations of information segments, which are obtained by equally dividing the information block prior to encoding. Grouped segments are then interleaved and encoded separately, while the information block is left uncoded. This novel sectionalization of the information sequence, combined with separate interleaving and encoding, bring the weight distribution closer to the binomial distribution of a random code. The effectiveness of the new technique is illustrated by the error performance of several symmetric and asymmetric 2-fold turbo codes in comparison with their equivalent turbo codes.
