We propose a technique for data detection in a two-dimensional page-access optical memory. The technique combines sequence detection by the use of the Viterbi algorithm with decision feedback to improve the bit-error-rate performance in a system corrupted by intersymbol interference. It has an advantage in that it can be operated on a row-by-row basis as data are output from the optical detector. Use of the proposed scheme might ease the design tolerances of the optical components or permit the use of large data pages.
我们提出了一种用于二维页面访问光学存储器中数据检测的技术。该技术将使用维特比算法的序列检测与判决反馈相结合，以提高在受码间干扰影响的系统中的误码率性能。其优势在于，当数据从光学探测器输出时，它可以逐行进行操作。所提出方案的使用可能会放宽光学组件的设计公差，或者允许使用大数据页面。
