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

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.
