Window-Interleaved Turbo Codes

We consider a class of turbo codes with a band structured interleaver, such that the interleaving (and thus deinterleaving) is done within a window. This ensures that the extrinsic information for each symbol is generated from symbols within a window, allowing the processing of large message blocks with a sliding window decoder. This provides flexibility in terms of decoding latency and also makes parallel decoding with high-throughput possible.
