Berrou, Glavieux and Thitimajshima combine interleaved recursive convolutional encoders with iterative soft-information decoding and report close-to-channel-limit error performance under a specified long-block Gaussian-channel simulation.
Scientific scope
Berrou, Glavieux and Thitimajshima combine interleaved recursive convolutional encoders with iterative soft-information decoding and report close-to-channel-limit error performance under a specified long-block Gaussian-channel simulation. Exact 1993 ICC conference paper 1064-1070/PDF 1-7 all original technical/annex/reference text read. Parallel recursive convolutional codes, interleaving and iterative extrinsic soft information use discrete Gaussian memoryless/binary-channel assumptions and approximate weak correlation/Gaussian feedback. Reported Monte Carlo uses rate 1/2, componentrate 2/3, constraintlength 5/16 states,65536-bit 256 x 256 interleaver,128 blocks and iterations up to 18. Close-to-limit headline is specific reported performance, not universal capacity/global convergence or hardware-efficiency proof. Low-SNR BER can worsen with iteration; weighting/interleaver choices and storage/delay matter. No exact headline Eb/N0 value or independently certified formula transcription is supplied here. Crossref date is null;1993 established by source copyright/conference identity. No independent certification.
