摘要
在分析现有光盘调制码的基础上,提出了一种新的RLL(2,12;8,15)编码。给出了码的构造方法和编解码步骤,并与几种常见的游程长度受限码进行了比较,分析了其优缺点,在FPGA上完成硬件实现。
Based on look -ahead technique, a new RLL （2, 12; 8, 15） run -length limited code is presented. The construction method of the code is discussed and the procedures in encoding and decoding of the code are also given. The major characteristic parameters of different run - length limited codes are compared; the decoder is implemented by FPGA.
