In this paper, four transmit beamforming (BF) techniques are selected and compared to realize inter-operator spectrum sharing, which is a promising solution for the spectrum shortage problem. The BF techniques include two game-theoretic (GT) algorithms, zero-forcing (ZF) and minimum mean square error (MMSE). After a brief description of the BF techniques in a multiple-input single-output (MISO) system,...
In this paper, we propose a precoding algorithm called flexible coordinated beamforming for the MIMO interference relay channel (IRC-FlexCoBF), where two base stations equipped with multiple antennas transmit to two user terminals simultaneously with the assistance of an amplify-and-forward relay that also has multiple antennas. The case of multiple data stream transmission is considered. The relay...
In this paper, single-stream transmission in the MIMO interference relay channel is studied. Two independent transceiver pairs with multiple antennas belonging to different operators communicate with the assistance of one relay, which operates in half-duplex mode and employs an amplify-and-forward strategy. The relay that is shared between the two operators also has multiple antennas. First, the interference...
