Design of LDPC Codes for the Unequal Power Two-User Gaussian Multiple Access Channel
, 2018 In this work, we describe an LDPC code design framework for the unequal power two-user Gaussian multiple access channel using EXIT charts. We show that the sum-rate of the LDPC codes designed using our approach can get close to the maximal sum-rate of ...

Optimized puncturing distributions for irregular non-binary LDPC codes
, 2010 In this paper we design non-uniform bit-wise puncturing distributions for irregular non-binary LDPC (NB-LDPC) codes. The puncturing distributions are optimized by minimizing the decoding threshold of the punctured LDPC code, the threshold being computed ...

Concatenated Turbo/LDPC codes for deep space communications: performance and implementation [PDF]
, 2013 Deep space communications require error correction codes able to reach extremely low bit-error-rates, possibly with a steep waterfall region and without error floor. Several schemes have been proposed in the literature to achieve these goals.

Spatially-Coupled MacKay-Neal Codes and Hsu-Anastasopoulos Codes
, 2011 Kudekar et al. recently proved that for transmission over the binary erasure channel (BEC), spatial coupling of LDPC codes increases the BP threshold of the coupled ensemble to the MAP threshold of the underlying LDPC codes.

Jointed LDPC codes design for half-duplex relay channels
Tongxin xuebao, 2013 In order to increase the coding gain of decode-and-forward half-duplex relay channel, a jointed LDPC coding structure and its corresponding optimization scheme was proposed. Novel structure made the subcodes of both source and relay nodes as parts of the
