Low-density parity check codes over GF(q)
TL;DR: A significant improvement over the performance of the binary codes is found, including a rate 1/4 code with bit error probability <10/sup -5/ at E/sub b//N/sub 0/=0.2 dB.
Proceedings ArticleDOI
Low density parity check codes over GF(q)
TL;DR: The results of Monte Carlo simulations of the decoding of infinite LDPC codes which can be used to obtain good constructions for finite codes and empirical results for the Gaussian channel are presented.
Book ChapterDOI
Evaluation of Gallager Codes for Short Block Length and High Rate Applications
TL;DR: This paper first explores the theoretical properties of binary Gallager codes with very high rates and observes that Gallager code of any rate offer runlength-limiting properties at no additional cost.
Low-Density Parity Check Codes over
TL;DR: A significant improvement over the performance of the binary codes, including a rate 1/4 code with bit error probability <10 at dB and the empirical results of error-correction using the analogous codes over for with binary symmetric channels and binary Gaussian channels.
Book ChapterDOI
Two Small Gallager Codes
TL;DR: A pair of Gallager codes with rate R = 1/3 and transmitted blocklength N = 1920 are presented as candidates for the proposed international standard for cellular telephones.
