GAO Jun-tao, HU Yu-pu, LI Xue-lian. A Relationship Between Autocorrelation and Linear Complexity[J]. Acta Electronica Sinica, 2006, 34(8): 1401-1404.DOI:
Autocorrelation and linear complexity are two independent criterions for measuring the pseudorandom properties of sequences.For the 2
emn-periodic pseudorandom sequences
we first present the relationship between autocorrelation and linear complexity.The relationship can be applied in the following two aspects:(1)Estimating/Evaluating the value of autocorrelation functions by the linear complexity;(2)Evaluating the correlation of a given sequence family by the linear complexity.Furthermore
for a sort of sequences with period 2
emn
we denote that the autocorrelation is related to linear complexity and
