Investigation of the influence of antenna array parameters on adaptive MIMO performance

The paper presents an investigation of the adaptive parameters of multi-antenna schemes for use in future reconfigurable MIMO systems. The study puts a special emphasis on linking the concept of channel diversity, either in the spatial or polarization domain, with the type of polarization being used, both at the transmitter (TX) and receiver (RX), and the level of multipath provided by the channel in the vertical or horizontal direction, with respect to the propagation plane. It has been found that NLOS indoor channels are very sensitive to the type of signal diversity being employed and the type of polarization and the multipath component being used.
