Let (Yn) be a sequence of i.i.d. real valued random variables. Reflected random walk (Xn) is defined recursively by X0=x ≥ 0, Xn+1 = |Xn - Yn+1|. In this note, we study recurrence of this process, extending a previous criterion. This is obtained by determining an invariant measure of the embedded process of reflections.
