A simple nonlinear model for the optical recording channel
H. Pozidis, W. Coene, Jan W. M. Bergmans · 2002
This study is concerned with the development of a simple yet sufficiently accurate model for the replay signal in optical discs. A method is proposed which models data storage (the write channel) as a nonlinear process and data retrieval (the read channel) as a linear one. The result is a low-complexity nonlinear model, of which the linear binary-PAM model is a special case. The performance of the proposed model is demonstrated by application to experimentally measured DVD data, and is found to be both accurate as well as robust to different recording media and conditions.
