摘要
本文提出的用于数字体全息数据存储系统的两种信道编码方法，不但可有效抑制系统中各种大尺度噪音的影响，而且有利于多重体全息图的均匀记录，并可简化存储器进行内容寻址操作时匹配阈值的设置．文章讨论了两种编码方法的实现复杂度，分析了其误码率性能．
Two channel--coding methods suitable for use in a digital volume holographic data storage system are presented. We could not only use the two techniques effectively to deal with various largescale noise,but also could result in more uniform recording of multiplexed volume holograms and could simplify the matching threshold determination in content--addressing operation. The system complexity and the bit error rate performance associated with the proposed methods are discussed.
