游程长度受限编码广泛应用于光(磁)存储系统中,通过将用户数据转换为符合特定信道约束的码元序列,从而提高数据传输的效率与可靠性。较为系统的介绍了游程长度受限编码的基本理论,从原理上分析了有限状态编码器与滑块分组译码器模型,并对主要的编码构造方法进行了概述,展望了游程长度受限编码的发展方向。
Run-length-limited coding is widely used in optical (magnetic) storage systems to improve the efficiency and reliability of data transmission by converting user data into sequences of symbols that conform to a particular channel constraint. The basic theory of run length limited coding is introduced systematically. The finite state coder and the block decoder model are analyzed theoretically. The main coding construction methods are summarized, and the run length limited coding The direction of development.
