Performance Improvement Using Iterative Two-Dimensional Soft Output Viterbi Algorithm Associated with Noise Filter for Holographic Data Storage Systems

초록

Demand of the data storage becomes more and more growing. This requests the next generation of storagedevices to have the dominated storage capability associated with superfast read/write rate. Holographic datastorage (HDS) is investigated for a long time and is considered to be a candidate for the future storage system. However, it has two-dimensional intersymbol interference that conventional one-dimensional detection solutionshave not yet handled strictly because of the complexity level of system as well as the cost. We propose a newscheme that combines iterative soft output Viterbi algorithm with noise filter for improving the bit error rateperformance of HDS.
