Abstract [en]

A class of Gaussian Z-interference channels with state is investigated in the regime of high state power with two transmitters communicating two independent messages through a "dirty" Z-interference channel with state. Transmitter 1 (primary user) interferes with receiver 2, while transmitter 2 (secondary user) does not interfere with receiver 1. In our model, we assume that both states are the same. Using lattice coding schemes, we obtain achievable rate-regions to characterize the boundary of the capacity region either fully or partially. Surprisingly, we observe that the achievable rate-region under a common state can include some points out of the rate-region when the channel is only corrupted by a state, i.e., when the additional interference is not harmful for the channel.
