| 摘 要： | A novel read channel for signal waveform modulation multi-level disc is presented in this paper.This read channel employs timing recovery system and partial response maximum likelihood detector.Compared to the previous read channel composed of level detection and run-length detection,the present read channel shows superiority in capacity increase and robust performance.Especially,relying on the partial response maximum likelihood detection,lower bit error rate can be obtained.

| Abstract: | A novel read channel for signal waveform modulation multi-level disc is presented in this paper. This read channel employs timing recovery system and partial response maximum likelihood detector. Compared to the previous read channel composed of level detection and run-length detection, the present read channel shows superiority in capacity increase and robust performance. Especially, relying on the partial response maximum likelihood detection, lower bit error rate can be obtained. |
