Design and Analysis of NB QC-LDPC Codes Over Small Alphabets

IEEE Transactions on Communications, 2022
We propose a novel approach to optimization of irregular nonbinary (NB) quasi-cyclic (QC)-LDPC codes over small alphabets. In this approach, first, the base parity-check matrices are constructed by a simulated annealing method, and then these matrices ...
