Abstract

This paper presents a new four-sampled zero crossing asymmetry compensation algorithm for high-speed DVD/CD applications. Simulations show 34% improvement of jitter performances, 50% reduction of compensation time and 2.0 dB gain of bit error rate (BER) compared with other algorithms. Simultaneously, a new digital timing recovery scheme for the optical drive system is presented. By comparative simulations using DVD patterns with marginal input conditions, the proposed timing recovery algorithm shows enhanced performances in jitter variance and SNR margin by 4 times and 3 dB respectively
