Linear Beamformingfor Multiple Operator MIMO One-Way Relayingwith Limited Feedback Responsible Professor: Supervisor: Prof. Martin Haardt Jianhui Li • Description:A multiple operator MIMO one-way relaying scheme is studied, where multiple transceiver pairs communicate with the assistance of an amplify-and-forward (AF) relay. • Tasks • Literature study on robust linear beamforming against channel quantization errors with limited feedback • Extension of current algorithm and compare to the conventional scheme • Novel robust beamforming design (optional) • References [1] B.
