Low-Complexity LDPC Codes with Near-Optimum Performance over the BEC
Recent works showed how low-density parity-check (LDPC) erasure correcting codes, under maximum likelihood (ML) decoding, are capable of tightly approaching the performance of an i...

Design of regular (2, dc)-LDPC codes over GF(q) using their binary images
In this paper, a method to design regular (2, dc)-LDPC codes over GF(q) with both good waterfall and error floor properties is presented, based on the algebraic properties of thei...

Quantization Effects in Low-Density Parity-Check Decoders
−A class of combinatorial structures, called absorbing sets, strongly influences the performance of low-density paritycheck (LDPC) decoders. In particular, the quantization schem...

Multi-user OFDM Based on Braided Convolutional Codes
Abstract Braided convolutional codes (BCCs) form a class of iteratively decodable convolutional codes that are constructed from component convolutional codes. In braided code divis...

Generalized and doubly generalized LDPC codes with random component codes for the binary erasure channel
In this paper, a method for the asymptotic analysis of generalized low-density parity-check (GLDPC) codes and doubly generalized low-density parity-check (D-GLDPC) codes over the b...
