| Abstract: | Based on the design of the relay beamforming matrix, an interference neutralization (IN) scheme is proposed for the two-cluster multi-user multiple-input multiple-output (MIMO) relay interference channel. First, the received signal at each relay is reconstructed by using the relay receive beamforming matrix. Then, each relay constructs the transmit beamforming matrix to eliminate the inter-cluster interference. The achievable degrees of freedom (DoF), the achievable sum rate and the application conditions for the IN scheme are analyzed. Experimental results have shown that the IN scheme can provide a significant DoF gain over the time division multiple access (TDMA) and the successive network coding (SNC) schemes. |
