This paper investigates the stability problem for discrete-time systems with time-varying delays. By employing the new integral inequality, a delay decomposition approach and Reciprocally Convex method, a novel criterion for stability is derived. Compared with some previous results, the new conditions obtained in this paper are less conservatism. Two numerical examples are given to show the effectiveness of the proposed methods.
