| In this paper, we jointly optimize the relay-precoders and decoders with partial channel side information (CSI) in a cooperative network. Specifically, two different CSI assumptions are considered: 1) full CSI at the destination terminal and partial CSI at the relay terminals; 2) partial CSI at the destination terminal and the relay terminals. We show that the optimum relay-precoders and decoders work in a fashion of channel selection. It is demonstrated by numerical results that the proposed optimum relay-precoders and decoders improve the performance considerably. | |||
