نویسندگان
چکیده
This document contains a first assessment of spatial transmission schemes regarding performance and complexity. In order to assess advanced beamforming and MIMO technologies, mathematical models, as well as methodologies for simulation and assessment have been developed. Conceptual work and simulation campaigns have been conducted. A baseline WINNER multi-antenna concept is proposed for further investigation based on multi-user spatial domain link adaptation consisting of the following basic components: linear dispersion codes, directive transmission (beamforming), multiuser precoding, and per stream rate control. Keyword list: beamforming, spatial diversity, spatial multiplexing, vector/matrix modulation, LDC, space time coding, opportunistic beamforming, SIMO, MISO, MIMO, switched beams, grid of beams, linear and non-linear precoding, link level simulations, system-level simulations, link-to-system level interface, spatial mode, multi-antenna concept.
