MIMO (Multiple Input Multiple Output) channels are known for some time now to offer either greater link gains or better spectral efficiency, depending on the correlation level of the scattering environment [1]. However, the benefits to be gained from the use of smarter antenna topologies do definitely not rule out gains available by the use of other techniques, such as polarisation diversity. T...

This paper investigates satellite-MIMO, space-time coded for diversity gain. Whereas a dual satellite to single antenna terminal link provides shadowing and some multipath diversity gain, a dual antenna terminal provides additional multipath diversity gain. This gain is demonstrated by simulating high resolution time series channel data for urban and highway environments, for SISO, MISO and MIM...

Organizations the world over is increasingly finding themselves coping with changes taking place in their environment. There are two sets of forces that changing once familiar organizational landscape increasing reliance on teams and workforce. This bringing more people from diverse backgrounds into contact one another. In general, diversity refers to ways organizations differ. That sounds simp...

in recent years reflectarray antennas have received considerable attention due to their unique capabilities. however, due to their large size, analyzing the performance of these antennas using traditional full wave finite-difference and finite-element techniques requires considerable computational resources. in this paper, we present an efficient method to accurately analyze these class of ante...

There have been many theoretical and experimental investigations on polarization diversity reception characteristics at base stations. The diversity gain was evaluated based on the distribution of the instantaneous received power in these investigations. The mainstream mobile communication systems are shifting to standardized IMT-2000 systems and the W-CDMA system is one of them. The effect usi...
