Abstract
When target densities of volume holographic data storage systems
are increased, the systems experience increased interference from
adjacent pixels and noise. Here we present a method for designing
and applying linear minimum mean-squared-error (LMMSE) equalization
to improve the bit error rates (BER’s) and hence the storage
densities achievable. Numerical results with five defocused data
pages indicate that a significant improvement in the BER is possible
with LMMSE equalization.
