In this paper, we investigate an efficient encoding approach for generalized low-density (GLD) parity check codes, a generalization of Gallager's low-density parity check (LDPC) codes. We propose a systematic approach to construct approximate upper triangular GLD parity check matrix which defines a class of efficient-encoding GLD codes. It's shown that such GLD codes have equally good performance. By effectively exploiting the structure sharing in the encoding process, we also present a hardware/software code-sign for the practical encoder implementation of these efficient-encoding GLD codes.
