  • Abstract
    We define the AWGNC, BSC, and max-fractional pseudocodeword redundancy p(C) of a code C as the smallest number of rows in a parity-check matrix such that the corresponding minimum pseudoweight is equal to the minimum Hamming distance of C. We show that most codes do not have a finite p(C). We also provide bounds on the pseudocodeword redundancy for some families of codes, including codes based on designs.
