Abstract

In this article, new classes of generalized cyclotomic binary sequences with period 2p m are proposed. We determine the linear complexity and autocorrelation of these sequences. The results show that the proposed generalized cyclotomic binary sequences have high linear complexity, but do not have desirable autocorrelation properties.
