Turbo codes are being investigated for magnetic recording channels. In contrast, relatively less attention has been devoted to the investigation of turbo decoding methods for optical data storage channels. In this paper, we present the simulation results of the performance of turbo decoding techniques in a partial response equalized optical data storage channel with transition noise. Our simulation results show that turbo codes with iterative decoding are robust to mark edge jitter, showing only a modest SNR loss even for 15% transition noise.
