Note about the linear complexity of new generalized cyclotomic binary sequences of period $2p^n$

This paper examines the linear complexity of new generalized cyclotomic binary sequences of period $2p^n$ recently proposed by Yi Ouang et al. (arXiv:1808.08019v1 [cs.IT] 24 Aug 2018). We generalize results obtained by them and discuss author's conjecture of this paper.
