چکیده:

In this paper, we compare the capacity bounds of fullduplex MIMO relay channel, by considering two cases for channel state information (CSI). In the first case, we assumethat the CSI is available at all nodes; in the second case, we consider that the CSI is only available at the receivers and thereis no information about the channel gains at the transmitters. Numerical results show that under certain constraint on the relay position with respect to the source and the destination, theavailability of CSI at the transmitters does not affect the capacity bounds. Thus, this simple result can be considered as apractical approach for constrained implementation of relaybased wireless networks
