The present invention relates to a method for demodulation of a data page in a holographic storage system, and to a holographic storage system using such method.
According to the invention, a method for demodulating a data page in a holographic storage system has the steps of:
- performing an adaptive learning process (20) for adapting a demodulation mechanism (17), and
- demodulating (30) the data page with the adapted demodulation mechanism.
For the adaptive learning process training data with known code words are used. The training data are correlated with the data acquired by the detector. The correlation step includes a principal axis transformation (PAT), a principal component analysis (PCA) and a K-nearest-neighbours (KNN) classification of the code blocks of the holographic data page.
