On noisy feedback for interference channels

An upper bound is established on the usefulness of noisy feedback for the interference channel (IC). The bound is based on the Hekstra-Willems dependence-balance arguments for two-way channels. For Gaussian ICs, the results suggest that feedback loses its efficacy roughly when the noise variance on the feedback link is larger than on the forward link.
