    • A method is disclosed for enforcing run-length limit constraints convolutional codes, comprising the steps of providing a desired run length limit constraint, providing a first convolutional code structure 202, processing data with the first convolutional code structure 202 such that convolutional code structure 202 applies a predetermined patterning to the data, evaluating and processing the data in reference to the desired run length limit constraint such that any of the data that is not compliant with the run length limit constraint is altered to become compliant, further processing said the data by a transceiver 206, providing a second convolutional code structure 204, evaluating the further processed data with convolutional code structure 204 in reference to the predetermined patterning such that data likely to have been previously altered is identified, and processing the further processed data with convolutional code structure 204 in reference to said predetermined patterning such that data identified as likely to have been previously altered is excluded.
    • 公开了一种用于执行游程长度限制约束卷积码的方法,包括以下步骤:提供期望的游程长度限制约束,提供第一卷积码结构202,使用第一卷积码结构202处理数据,使得卷积码结构202适用 对数据进行预定的图案化,参考期望的游程长度限制约束来评估和处理数据,使得不符合游程长度限制约束的任何数据被改变以变得兼容,进一步处理所述数据 收发器206,提供第二卷积码结构204,参考预定图案化,利用卷积码结构204评估进一步处理的数据,以便识别出可能已经改变的数据,并用卷积码结构204处理进一步处理的数据 参考所述预定图案化 确定可能已被更改的数据被排除在外。
