Abstract
In DVD-ROM, how to equalize the read-out radio frequency (RF) signal to reduce the jitter ratio has been an important issue so far. In this paper, we investigate the characteristic of the optical channel model in DVD-ROM and propose an Adaptive Neuro-Fuzzy Inference System (ANFIS) based equalizer together with a viterbi detector to form as a partial response maximum likelihood (PRML) system for DVD-ROM. Jitter performance using ANFIS based equalizer is compared with that of other linear filter based equalizers. By computer simulation, it shows that the proposed equalization method has better jitter performance than conventional linear filter based equalizers for the optical channel in DVD-ROM.
