摘　　要：从高阶累积量入手,引出了m序列的三阶相关函数,利用m序列峰值图案的唯一性得到生成多项式,从而估计m序列。还讨论了利用m序列片段的三阶相关函数从部分m序列中恢复完整m序列的方法,仿真结果也证明了该方法的可行性。The triple correlation function of m sequence is presented after a fast view on high-order statistic. First the generation polynomial, then the m sequence, is estimated based on the uniqueness of the peak pattern of m sequence. The method of resuming complete m sequence from part of m sequence, which based on the m sequence fraction triple correlation function, is also presented. The practicality of this method is proved by the satisfying simulation result.
