PARALLEL DATA DETECTION IN PAGE-ORIENTED OPTICAL MEMORY

We discuss a novel two-dimensional parallel technique for reliable dat a detection in page-oriented optical memories. The method is motivated by decision feedback techniques and is fully parallel, offering conve nient, locally connected electronic implementation. The algorithm is s hown to offer significant improvements over simple threshold detection and in some cases can approach the maximum-likelihood bound of data r eliability.
