摘要
介绍了一种新的用于高密度光盘存储的游程长度受限码。给出RLL(4,18)码的构造方法和编解码步骤。对RLL(4,18)码的编码器和解码器进行了CPLD实现。对不同游程长度受限码的主要性能参数进行了比较。
A new run-length limited code is introduced. The construction, encode and decode method of the RLL(4,18) code are discussed. The encoder and decoder of the RLL(4,18) code are implemented by CPLD. The major characteristic parameters of different run-length limited codes are compared.
