Constrained Error Pattern Generation for GRAND
Mohammad Rowshan, Jinhong Yuan
Maximum-likelihood (ML) decoding can be used to obtain the optimal performance of error correction codes. However, the size of the search space and consequently the decoding comple…
Efficient Partial Rewind of Polar Codes' Successive Cancellation-based Decoders for Re-decoding Attempts
Mohammad Rowshan, Emanuele Viterbo
Successive cancellation (SC) process is an essential component of various decoding algorithms used for polar codes and their variants. Rewinding this process seems trivial if we ha…
On Convolutional Precoding in PAC Codes
Mohammad Rowshan, Emanuele Viterbo
Polarization-adjusted convolutional (PAC) codes are special concatenated codes in which we employ a one-to-one convolutional transform as a precoding step before the polar transfor…
List Viterbi Decoding of PAC Codes
Mohammad Rowshan, Emanuele Viterbo
Polarization-adjusted convolutional (PAC) codes are special concatenated codes in which we employ a one-to-one convolutional transform as a pre-coding step before the polar transfo…
Shifted Pruning for List Decoding of Polar Codes
Mohammad Rowshan, Emanuele Viterbo
In successive cancellation list (SCL) decoding, the tree pruning operation retains the L best paths with respect to metric at every decoding step. However, the correct path might b…
