Experimental Investigation of GF(3(exp 2)) Nonbinary LDPC-coded Non-uniform 9-QAM Modulation Format

摘要

A specially designed GF(32) nonbinary LDPC-coded non-uniform 9-quadrature amplitude modulation (QAM) is proposed. The experimental and numerical results show that the proposed scheme outperforms nonbinary GF(2(exp 3)) LDPC-coded uniform 8-QAM by ~0.8-dB.
