  • The design of transceivers in relaying systems is studied with full Channel State Information (CSI) or partial CSI at the relay. Based on the acquired CSI,the relay filters and retransmits its received signals and the destination recovers the original signals with linear Minimum Mean Square Error (MMSE) receiver. Simulation results show that the proposed relaying scheme is prior to the traditional Amplify-and-Forward (AF) relaying. At high Signal to Noise Ratio (SNR), the scheme based on partial CSI feedback behaves closely to that based on full CSI feedback.
