  1. 1. Machine Intelligence in Decoding of Forward Error Correction Codes

    University essay from KTH/Teknisk informationsvetenskap

    Author : Navneet Agrawal; [2017]
    Keywords : ;

    Abstract : A deep learning algorithm for improving the performance of the Sum-ProductAlgorithm (SPA) based decoders is investigated. The proposed Neural NetworkDecoders (NND) [22] generalizes the SPA by assigning weights to the edges ofthe Tanner graph. We elucidate the peculiar design, training, and working of theNND. READ MORE

  3. 2. Efficient Decoding Algorithms for Low-Density Parity-Check Codes

    University essay from Institutionen för systemteknik

    Author : Anton Blad; [2005]
    Keywords : Electronics; LDPC; Low Density Parity Check; Tanner graph; decoding; sum-product; probability propagation; early decision; threshold; Elektronik;

    Abstract : Low-density parity-check codes have recently received much attention because of their excellent performance and the availability of a simple iterative decoder. The decoder, however, requires large amounts of memory, which causes problems with memory consumption. READ MORE
