Performance comparison of detectors for DVD channel impaired by bloom and transition noise

Abstract

The performance of several detectors for digital video disk (DVD) channel suffering from linear intersymbol interference, bloom, transition noise and additive Gaussian noise was evaluated. The detectors include the non-Viterbi detectors which exploit the d = 2 run-length constraint of the EFMPlus code in the DVD channel, and also the Viterbi detectors following equalization to certain partial response targets. The proposed detection scheme uses a partial response target of memory 6, but accounts for the resulting destructive interference through run-length corrections.
