| Abstract | We consider the robust design of a millimeter wave MIMO two-hop system in which source, relay and destination areequipped with large antenna arrays. The relay implements the amplify-and-forward protocol and operates in full-duplex mode,thus being subjected to self-interference (SI). Imperfect channel state information (CSI) is assumed in all involved links, includingthe SI channel, with a deterministic isotropic bounded model on CSI errors. The proposed robust design seeks to maximizethe worst-case spectral efficiency, accommodates both digital and phase shifter-based analog beamforming, and is computationallysimple; moreover, it does not require knowledge of the size of the CSI uncertainty regions. |
