摘要

全息数据存储（HDS）系统信号处理的主要问题是二维（2D）符号间干扰（ISI），这种干扰来自 HDS 系统数据页面上各个方向的相邻像素。最近，有人提出了用于比特图案介质记录（BPMR）的串行-并行检测。我们意识到，串行-并行检测结构比 BPMR 系统更适合 HDS 系统，因为与 BPMR 系统不同，HDS 系统中来自水平和垂直方向的干扰是相等的。因此，用于 HDS 系统的串行并行结构可以获得更好的误码率性能。

Parallel detection structure exploiting the extrinsic information from the serial detection in the holographic data storage system

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.
