Upper bounds on the rate of LDPC Codes
We derive upper bounds on the rate of low density parity check (LDPC) codes for which reliable communication is achievable. We first generalize Gallager's bound to a general ...

Split-Row: A Reduced Complexity, High Throughput LDPC Decoder Architecture
— A reduced complexity LDPC decoding method is presented that dramatically reduces wire interconnect complexity, which is a major issue in LDPC decoders. The proposed Split-Row m...

On the Block Error Probability of LP Decoding of LDPC Codes
Abstract-- In his thesis, Wiberg showed the existence of thresholds for families of regular low-density parity-check codes under min-sum algorithm decoding. He also derived analyti...

Structure of non-binary regular ldpc cycle codes
In this paper, we study non-binary regular LDPC cycle codes whose parity check matrix has fixed column weight 2 and fixed row weight d. We prove that the parity check matrix of ...

Near-Shannon-Limit Linear-Time-Encodable Nonbinary Irregular LDPC Codes
—In this paper, we present a novel method to construct nonbinary irregular LDPC codes whose parity check matrix has only column weights of 2 and t, where t ≥ 3. The constructed...
