Weight and Trapping Set Distributions for Non-Binary Regular Low-Density Parity-Check Code Ensembles

The variances of weight and trapping set distributions of non-binary regular low-density parity-check ensembles are derived. Using the second moment method, bounds on the probabilities that a randomly chosen code from the ensemble has its weight and trapping set distributions close to the ensemble a...

Description
Summary:The variances of weight and trapping set distributions of non-binary regular low-density parity-check ensembles are derived. Using the second moment method, bounds on the probabilities that a randomly chosen code from the ensemble has its weight and trapping set distributions close to the ensemble averages are obtained.
