On the designand performance of nonbinary LDPC codes on burst errorchannels
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 e (SBE) channels...

| Summary: | 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 e (SBE) channels and burst-deep-fading additive white Gaussion noise (BF-AWGN) channels respectively. Two criteria of designing QLDPC codes were presented for burst er-ror channels. Moreover, a class of structured extended -ary irregular repeat-accumulate (S-eQIRA) codes was proposed,Q 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. |
