Capacity performances of Space-Time Beamformers for space-time arrayed VIVO DS-CDMA system

摘要

Multi-Users system technology, array processing and Space-Time Beamforming are recent methods invented for wireless communication schemes. An Arrayed Vector-Input, Vector-Output (VIVO)DS-CDMA system is treated in this paper. We treat in particular the capacity of Multi-Users detectors using Beamforming technology. At this stage, a new mathematical formulation in terms of capacity for various Space-Time Beamformers is developed in this work. A performances capacity evaluation according to the various parameters which manage wireless communications over Arrayed VIVO DS-CDMA system environment is carried out for this reason.
