PSTD for Shared Data Channels: A Critical Analysis
01 January 2003
In this paper we propose a promising multi-antenna for share channel users, which provides the benefits of beamforming without the requirement of channel state information at the transmitter. In this scheme, called PSTD (Phase Swept Transmit Diversity), a periodic phase difference is applied between antennas in the Base Station (BS) array on all signals (traffic and pilot) transmitted.
