| 摘 要： | 本文着重讨论计算机辅助设计RLL码的具体实现问题.该过程首先根据RLL码两个参数d,k确定一个编码率p/q,然后构造出RLL码的高阶状态转换-输出符号矩阵并求相应的近似特征向量.最后通过状态分裂和状态归并过程,即可得到一个满足d,k约束的编码输出表.其中状态转换-输出符号矩阵为实现计算机辅助设计RLL码提供了有效的数据结构,而且要优化RLL码编码器,就必须有选择地进行状态分裂.

| Abstract: | This article discusses the concrete implementation of computer- aided design of RLL codes. The procedure first chooses coding rate p/c according to the parameters d and k of RLL codes. Then, the higher order state transition-output symbol matrix is constructed and corresponding approximate characteristic vector is worked out. Finally an encoding output table of RLL codes satisfying the d and k constraints is obtained from state splitting and state merging. |

| Keywords: | Coding rate channel capacity state transition output symbol approximate characteristic vector state splitting state merging. |
