Abstract
We study LDPC codes for the channel with input and output . The aim of this paper is to evaluate decoding performance of -ary non-binary LDPC codes for large . We give density evolution and decoding performance evaluation for regular non-binary LDPC codes and spatially-coupled (SC) codes. We show the regular codes do not achieve the capacity of the channel while SC codes do.
