Abstract

In this paper downlink beamforming for cellular radio systems with frequency division duplex (FDD) is optimized. System level simulations shall clarify what gain can be achieved by applying circular arrays with omnidirectional antenna elements in contrast to linear arrays with sectorizing antenna elements. Furthermore, the parameters of the antenna arrays like element spacing and beamwidth of the sector antennas are optimized
