  • Abstract
    Protograph-based doubly generalized LDPC (DGLDPC) codes are explored in this paper. We extend (and in the process simplify) the technique for computing the ensemble weight enumerators of protograph-based LDPC and GLDPC codes to DGLDPC codes. We find that with careful design, protograph-based DGLDPC codes can have a better asymptotic growth rate of minimum distance than that of the protograph-based LDPC and GLDPC codes. Simulation results confirm that protograph-based DGLDPC codes have a low error floor.
