Abstract
The major concern in signal processing for holographic data storage (HDS) systems is the two-dimensional (2D) inter-symbol interference (ISI), which arises from neighboring pixels in every direction on the data page of HDS systems. Recently, serial–parallel detection has been proposed for bit-patterned media recording (BPMR). We have realized that the serial–parallel detection structure is more suitable for HDS systems than BPMR systems, because, unlike BPMR systems, the interferences in HDS systems from horizontal and vertical directions are equal. Therefore, the serial–parallel structure for HDS systems can extract better bit-error-rate performance.
