摘要：
In cellular mobile radio systems, transmit beamforming can be used to reduce the interference in the downlink. In a Time Division Duplex (TDD) system with sufficiently short duplex period, the uplink channel estimation can be used to design the downlink beamformer. The purpose of this paper is to analyse the sensitivity of several transmit techniques to the channel variations between uplink and downlink time-slots. This analysis is done using experimental data obtained from real environments.
