Abstract(in English) | Cooperative distributed antenna transmission (CDAT) can mitigate the impact of path loss, shadowing loss, and multi-path fading by adaptively choosing multiple distributed antennas close to user equipment (UE) and achieves a high link capacity. The CDAT is an advanced version of the coordinated multi-point (CoMP) transmission. Recently, we proposed a minimum mean square error filtering combined with singular value decomposition (MMSE-SVD) for multi-user spatial multiplexing and showed that it can achieve higher sum capacity than the use of conventional MMSE precoding. In cellular systems, since the same carrier-frequency is re-used by different macro base stations (MBSs), co-channel interference (CCI) from adjacent MBSs limits the capacity. In this paper, we modify the MMSE-SVD so as to take into account the CCI from adjacent macro-cells. We evaluate by computer simulation the achievable downlink sum capacity with the modified MMSE-SVD in a multi-cell environment and show that MMSE-SVD achieves higher capacity with lower computational complexity than the block diagonalization combined with SVD (BD-SVD). |
