A Fresh Look at Coding for q-ary Symmetric Channels
Claudio Weidmann, Gottfried Lechner
This paper studies coding schemes for the -ary symmetric channel based on binary low-density parity-check (LDPC) codes that work for any alphabet size , ,…
Growth Rate of the Weight Distribution of Doubly-Generalized LDPC Codes: General Case and Efficient Evaluation
Mark F. Flanagan, Enrico Paolini, Marco Chiani +1
The growth rate of the weight distribution of irregular doubly-generalized LDPC (D-GLDPC) codes is developed and in the process, a new efficient numerical technique for its evaluat…
On a Class of Doubly-Generalized LDPC Codes with Single Parity-Check Variable Nodes
E. Paolini, M. F. Flanagan, M. Chiani +1
A class of doubly-generalized low-density parity-check (D-GLDPC) codes, where single parity-check (SPC) codes are used as variable nodes (VNs), is investigated. An expression for t…
Two-Bit Message Passing Decoders for LDPC Codes Over the Binary Symmetric Channel
Lucile Sassatelli, Shashi Kiran Chilappagari, Bane Vasic +1
In this paper, we consider quantized decoding of LDPC codes on the binary symmetric channel. The binary message passing algorithms, while allowing extremely fast hardware implement…
