Abstract

- Interference management is required for improving the performance of future mobile radio communication systems. In the downlink (DL) of cellular systems with base stations (BSs) located in the cell centers and equipped with omnidirectional antennas, transmission strategies such as matched filtering (MF) can’t achieve good system performance, and zero forcing (ZF) with full channel state information (CSI) of the whole system imposes a high computational cost and requires a substantial amount of feedback. In this paper, an intelligent signal processing technique with moderate complexity, i.e., ZF joint transmission (JT) with significant CSI, based on distributed antenna systems (DASs) with BSs located at three vertices of each cell and equipped with sector antennas is proposed. From numerical results, it is shown that our proposal is a good combination of BS antenna layout and signal processing technique for inter- ference management. The proposed intelligent signal processing technique can significantly benefit from the proposed smart BS antenna layout.
