Future wireless communication systems are expected to support a wide range of services which include video, data and voice. To achieve the necessary capacity for these systems, several smart antenna systems have been proposed and demonstrated at the base station of wireless communication systems. In this thesis, the performance of using smart or adaptive antennas at the base and mobile stations in both the down and uplinks is investigated. In addition, the application of this smart antenna systems to orthogonal frequency division multiplexing is also considered.

Future wireless communication systems are expected to support a wide range of services which include video, data and voice. To achieve the necessary capacity for these systems, several smart antenna systems have been proposed and demonstrated at the base station of wireless communication systems. In this thesis, the performance of using smart or adaptive antennas at the base and mobile stations in both the down and uplinks is investigated. In addition, the application of this smart antenna systems to orthogonal frequency division multiplexing is also considered. The advantages of the proposed system include reductions in average error probability and increases in capacity. To demonstrate the potential of the proposed smart antenna system, analytical along with Monte Carlo simulation results are provided. Simulation results reveal that a reduction in average error probability of up to 100 times can be achieved by utilizing smart antennas at the base and mobile stations in the up and downlinks compared to a smart antenna system at the base station only.
