　　根据补偿码的性质、构码规则，发现其规律性，进一步化简，省略了更长CCK码构码中繁琐的交叉分解运算，进而给出了32位、64位、128位CCK码的构造方法，工程技术人员可以拿来直接使用；为了应用的便利性，首先分析其相关特性，得出最大互相关比例随码长增加变小、正交比例随码长增加变大的规律；仿真显示，CCK调制的误码性能随着码长的增加越来越好。

upon the theory of multiphase complementary code, search the rule, and predigest it, overleap cross operation in course to construct expanded CCK modulation. Provide method to construct CCK32, CCK64, CCK128 etc. Firstly, the correlation property are analyzed, aftermath is educed, that most scale of cross-correlation is trail-off along with length fill-out, and scale of orthogonal is fill-out along with length fill-out. The expanded CCK modulation can obtain considerable improvement in the bit error rate performance, and longer length gets the better performance.
