Multicell Cooperation Based SVD Assisted Multi-User MIMO Transmission

In this treatise, we investigated the application of singular value decomposion (SVD) assisted multiuser transmis- sion in a multicell scenario. The SVD based scheme is capable of completely removing the cochannel interference, similarly to the classic zero forcing (ZF) based and block diagonalization (BD) aided schemes. Two different power allocation schemes are investigated for both SVD, ZF and BD based multicell transms- sion. The SVD scheme achieves a suboptimal performance, but at a reduced complexity. Nonetheless, it always outperforms the ZF based scheme due to the joint reception of the transmitted symbols.
