Linear minimum mean squared error (LMMSE) equalization for holographic data storage

A holographic data storage system (HDSS), just like other storage systems, suffers from interference between adjacent symbols and from noise. In this paper, we present a method for applying the linear minimum mean squared error (LMMSE) equalization to a HDSS. Numerical results with five defocused pages of data indicate that a significant improvement in the bit error rate (BER) is possible using LMMSE equalization.
