So the iterative times are reduced greatly. By optimized iterative algorithm, the speed of decoding BCHcodes gets increased obviously.
通过使用优化的迭代算法，可以使得整个二元BCH码的译码速度得到明显的提高。

BCHcodes are a subset of the class of linear block codes that have good error correction capability. Information hiding is a new technique in information security field.
BCH纠错编码是线性分组码的一种，有较好的纠错能力，信息隐藏是近年来信息安全领域出现的新技术。
