A generalization of Carleson's theorem concerning series with respect to systems $\{\varphi(nx)\}$ is proved for the case in which $\varphi(x)$ can be expanded in an absolutely convergent Fourier series. Systems corresponding to functions $\varphi(x)$ which have lacunary Fourier series are studied in detail.
