Weight and Stopping Set Distributions of Two-Edge Type LDPC Code Ensembles
Ryoji Ikegaya · IEICE Transactions on Fundamentals of Electronics Communications and Computer Sciences · 2005
In this paper, we explicitly formulate the average weight and the stopping set distributions and their asymptotic exponents of two-edge type LDPC code ensembles. We also show some characteristics such as the symmetry and the conditions for zero of the weight distributions of two code ensembles. Further we investigate the relation between two code ensembles from the perspectives of the weight and stopping set distributions.
