Title
Linear complexity of periodically repeated random sequences
Abstract
On the linear complexity Λ(z) of a periodically repeated random bit sequence z, R. Rueppel proved that, for two extreme cases of the period T, the expected linear complexity E[Λ(z)] is almost equal to T, and suggested that E[Λ(Z)] would be close to T in general [6, pp. 33- 52] [7, 8]. In this note we obtain bounds of E[Λ(Z)], as well as bounds of the variance Var[Λ(Z)], both for the general case of T, and we estimate the probability distribution of Λ(Z). Our results on E[Λ(Z)] quantify the closeness of E[Λ(Z)] and T, in particular, formally confirm R. Rueppel's suggestion.
