摘要

The benefits of partial and full transmitter cooperation are evaluated for a two user interference channel under finite precision channel state information at the transmitters (CSITs), using the generalized degrees of freedom (GDoFs) metric. Under finite precision CSIT, the benefits of interference alignment are completely lost, so that the channel obtained by partial transmitter cooperation does no better than the underlying interference channels. Full transmitter cooperation produces a vector broadcast channel, which has a strict GDoF advantage over partial cooperation ( channel) and whose GDoF is fully achieved by interference enhancement.
