Short ldpc codes
SpletControlling small size trapping sets and short cycles can result in LDPC codes with large minimum distance d_min. We prove that short cycles with a chord are the root of several … SpletIn this section, we briefly introduce these codes and evaluate their performance to finally answer the question which channel code is the best for short underwater messages in …

Spletand constructed check-hybrid GLDPC codes using Hamming codes as component codes. In another work by Liva et al. [7], low-rate GLDPC codes are constructed by doping quasi-cyclic (QC)-LDPC codes with Hamming codes. It was shown that the constructed codes have a remarkable performance both in the waterfall and the error-floor regions on the ...
