—The increasing interest in MIMO (Multiple-Input Multiple-Output) systems has given rise to a proliflc research activity in recent years. Both theoretical and practical issues have been studied. However, so far few MIMO testbeds or prototypes have been built for DVB-T or future standards. In this paper, a novel 2x2 MIMO testbed speciflcally designed for… (More)
This paper proposes several configurations for multiple base stations in indoor MIMO systems and compares their performance. The results are based on channel measurements realized with a MIMO testbed. The receiver was moved along several routes and floors on an office building. Both outdoor and indoor locations are considered for the transmitters or base… (More)
In this paper, we compute the uplink capacity of a W-CDMA 3-D air-to-ground (AG) " cellular like " network. The capacity of the system depends on both the cell height and the cell radius.
The capacity gain of frequency diversity spread spectrum system (FDSS) overlaid on top of a narrow band code division multiplexing access system (N-CDMA) system is estimated. The carrier to interference ratios (CIR`s) of both the (FDSS) and (N-CDMA) systems are evaluated. It is assumed that the base stations of both systems are unilocated and that the power… (More)
