We introduce an ensemble of quasi-regular low-density parity check error control codes we
call/spl pi/-rotation LDPC codes. These codes are completely defined by a single …

This paper presents a new method to design low-density parity-check codes for a variety of
different rates that all share the same fundamental decoder architecture. Combining rows of …

This paper describes and analyzes low-density parity-check code families that support
variety of different rates while maintaining the same fundamental decoder architecture. Such …

In the past few years, Gallager's low-density parity-check (LDPC) codes received a lot of
attention and many efforts have been devoted to analyzing and improving their error …

An ensemble of'π-rotation'low-density parity check codes, extending the result in previously
reported work by a different team of authors, is introduced. The key features of these codes …

This letter presents a systematic and recursive method to construct good low-density parity-
check (LDPC) codes, especially those with high rate. The proposed method uses a parity …

Low density parity check (LDPC) codes with iterative decoding based on belief propagation
(IDBP) achieve astonishing error performance close to the Shannon limit. Until now there …

Low-density parity-check (LDPC) codes have been shown to have good error correcting
performance approaching Shannon's limit. Good error correcting performance enables …

A novel parity-check matrix design for low-density parity-check (LDPC) codes is described.
By eliminating the routing problem associated with LDPC codes, the design results in a …
