Abstract :
In this paper a channel model is proposed for two-dimensional digital data storage systems. This channel model describes both the intersymbol interference structure and the noise structure. This noise structure is modelled as the output of a two-dimensional data-dependent autoregressive filter. The proposed model is simple, accurate and it is able to track channel variations. An experimental two-dimensional optical system is used to validate the proposed model and to illustrate the characterization process based on the model
