Abstract :
We analyze different space-time architectures for the TDD mode of UTRA when employing multi-element antenna arrays at both the transmit and receive sites. We compare space-time codes that do not require channel knowledge at the transmitter with a beamforming scheme, which exploits channel reciprocity available in the TDD mode to construct a beamvector at the transmitter.
