Abstract
This paper presents a method for evaluating pseudocodeword weight enumerators of nonbinary LDPC codes built out of protographs. The ensemble enumerators are evaluated for both the finite-length and infinite-length regimes. Results of this type can be particularly useful for designing structured non-binary LDPC codes with good properties under message passing or linear programming decoding.
