Design of two way multiantenna AF relay systems under perfect CSI
Tomohiro Taniguchi, Yoshio Karasawa, Nobuo Nakajima · European Conference on Antennas and Propagation · 2010
This paper presents design methods of two way AF (amplify and forward) relay systems equipped with multiantenna assuming perfect knowledge of CSI (channel state information). A simple SVD (singular value decomposition) based method using separable relay weights and an iterative design based on maximum SINR (signal to interference plus noise ratio) criterion adopting nonseparable relay weights are considered. Throught computer simulations, their peformances under fading channels are investigated.
