Les taux d'erreur sur les bits (BER) pour la lecture du code (1,7) utilisé dans l'enregistrement sur disque optique ont été simulés à l'aide d'une forme d'onde de lecture idéale (gaussienne), la lecture étant effectuée par PRML (Partial Response Maximum-Likelihood) combinant un égaliseur à réponse partielle et un décodeur Viterbi à double horloge. Il a été constaté que le meilleur BER se produit pour le décodage de Viterbi au niveau PR(2,3,3,2) +7/10 à une valeur pondérée de w = 0.5 pour les données composées de 107 symboles. Pour une longueur de bit minimale de 0.28 µm, BER de 10-4 et moins de 10-6 a été obtenu pour des rapports SN de 15.6 dB et 17.7 dB, respectivement. Et pour une longueur de bit minimale de 0.26 µm, BER de 10-4 et moins de 10-6 a été obtenu pour des rapports SN de 16.7 dB et 18.8 dB, respectivement. Ces résultats démontrent la faisabilité d'une longueur de bit minimale de 0.26 µm dans les enregistreurs de disques optiques actuels.

Abstract: Bit error rates (BER) for playback of (1,7) code employed in optical disc recording were simulated using an ideal (Gaussian) playback waveform, with playback being performed by PRML (Partial Response Maximum-Likelihood) combining a partial response equalizer and a double clock weighted Viterbi decoder. It was found that best BER occurs for PR(2,3,3,2) +7/10 level Viterbi decoding at a weighted value of w = 0.5 for data consisting of 107 symbols. For a minimum bit length of 0.28 µm, BER of 10-4 and less than 10-6 was obtained for SN ratios of 15.6 dB and 17.7 dB, respectively. And for a minimum bit length of 0.26 µm, BER of 10-4 and less than 10-6 was obtained for SN ratios of 16.7 dB and 18.8 dB, respectively. These results demonstrate the feasibility of a minimum bit length of 0.26 µm in current optical disc recorders.
