We analyze current auto- and cross correlations in the system of two capacitively coupled large quantum dots. Our attention is focused on the strong inter dot coupling when an electron transfer through one of the quantum dots induces charge pumping through the second quantum dot. We show individual contributions to shot noise from various tunneling processes in the charge space.
