Research on unequal error protection of irregular LDPC codes
Tongxin xuebao, 2005 An irregular low-density parity-check （LDPC） code with unequal error protection （UEP） property was proposed. A weight-increasing parity-check （WIPC） matrix was constructed.

Encoding of QC-LDPC Codes of Rank Deficient Parity Matrix
Journal of Engineering, 2016 the encoding of long low density parity check (LDPC) codes presents a challenge compared to its decoding. The Quasi Cyclic (QC) LDPC codes offer the advantage for reducing the complexity for both encoding and decoding due to its QC structure.

Low-Floor Tanner Codes via Hamming-Node or RSCC-Node Doping [PDF]
, 2006 We study the design of structured Tanner codes with low error-rate floors on the AWGN channel. The design technique involves the “doping” of standard LDPC (proto-)graphs, by which we mean Hamming or recursive systematic convolutional (RSC) code ...

Efficient Helicopter-Satellite Communication Scheme Based on Check-Hybrid LDPC Coding
Tsinghua Science and Technology, 2018 When implementing helicopter-satellite communications, periodical interruption of the received signal is a challenging problem because the communication antenna is intermittently blocked by the rotating blades of the helicopter.

A Decoding Algorithm for LDPC Codes Over Erasure Channels with Sporadic Errors [PDF]
, 2010 An efficient decoding algorithm for low-density parity-check (LDPC) codes on erasure channels with sporadic errors (i.e., binary error-and-erasure channels with error probability much smaller than the erasure probability) is proposed and its performance ...

Protograph EXIT Analysis over Block Fading Channels with Application to Relays [PDF]
, 2012 An accurate extrinsic information transfer (EXIT) analysis is developed for protograph low-density parity-check (LDPC) codes over the block fading channel (BFC). The analysis is thus exploited for analyzing the behavior of distributed protograph LDPC
