Optimization of NB QC-LDPC Block Codes and Their Performance Analysis
Irina E. Bocharova, Boris D. Kudryashov, Evgenii P. Ovsyannikov +2
We propose an approach for optimizing nonbinary (NB) quasi-cyclic (QC) LDPC codes. This approach combines constructing of base parity-check matrices by simulated annealing and labe…
