ABSTRACT
Let $(S_{n})_{n\in{ N}}$ be a $Z$-random walk on nearest neighbours with dynamical quasiperiodic transition probabilities in a random scenery $\xi(\alpha),\alpha\in Z$, that is a family of i.i.d. random variables, independent of the random walk. It is shown that $\displaystyle n^{-\frac{3}{4}}\sum_{i=0}^{[nt]} \xi(S_{i})$ converges weakly as $n\rightarrow \infty$ to a self-similar process with stationary increments.
