Abstract
A random array exclusive OR modulation (REOM) channel coding technique is proposed for digital holographic data storage. The effect of channel coding on the system performance is analyzed through simulations. The performance of REOM is compared with that of other coding methods in terms of system raw bit error rate (BER) and signal-to-noise ratio (SNR). It is shown that REOM provides relatively uniform intensity distribution on the recording plane and therefore gives an improved performance.
