  Using a quantum map version of one-dimensional Anderson model, the
localization-delocalization transition of quantum diffusion induced by coherent
dynamical perturbation is investigated in comparison with quantum standard map.
Existence of critical phenomena, which depends on the number of frequency
component $M$, is demonstrated. Diffusion exponents agree with theoretical
prediction for the transition, but the critical exponent of the localization
length deviates from it with increase in the $M$. The critical power
$\epsilon_c$ of the normalized perturbation at the transition point remarkably
decreases as $\epsilon_c \sim (M-1)^{-1}$.
