基于采样和交织技术,研究了周期为4 N的最佳自相关幅度二元序列的构造。根据特征多项式之间的内在联系,我们确定了所构造序列的线性复杂度的精确值,并证明了它为2N+2。此外,我们还通过自相关函数确定了这些序列的2-adic复杂度,并证明了它可以达到最大值。实验结果表明,该序列能抵抗Berlekamp-Massey攻击和有理逼近算法,并且具有良好的通信性能。
A construction of binary sequences with period $ 4N $ and optimal autocorrelation magnitude has been investigated based on sampling and interleaving technique. We determine the exact value of the linear complexity of the constructed sequences according to the deep relationship among the characteristic polynomials, and show it is $ 2N+2 $. Moreover, we determine the 2-adic complexity of these sequences by the autocorrelation function, and show it can attain the maximum value. Results show that such sequences can resist both the Berlekamp-Massey attack and the Rational Approximation Algorithm, in addition are good for communication.
