摘要: 分析比较了结构化非规则多元重复累计码、Turbo码和二元LDPC码在单突发删除信道和高斯突发深衰落信道上的纠错性能,同时提出了QLDPC在突发信道下的两条设计准则。针对突发信道设计了一类扩展型S-QIRA码—S-eQIRA,并在单突发删除信道和高斯突发深衰落信道上进行仿真,仿真结果表明该码字具有较强的纠突发错误能力。
Abstract: Taking structured Q-ary irregular repeat-accumulate (S-QIRA) codes as an example, the burst-error-correcting capability of QLDPC codes was analyzed preliminarily by comparison with the burst-error-correcting capability of binary LDPC codes (BLDPC)and turbo codes on the single burst erasure (SBE) channels and burst-deep-fading additive white Gaussion noise (BF-AWGN) channels respectively. Two criteria of designing QLDPC codes were presented for burst error channels. Moreover, a class of structured extended Q-ary irregular repeat-accumulate (S-eQIRA) codes was proposed, which performs rather well on burst error channels. Numerical results indicate that, the proposed S-eQIRA codes have higher burst-error-correcting capability on both SBE and BF-AWGN channels.
