Analysis and simulation of smart antennas for GSM and DECT in indoor environments based on ray launching modeling techniques

A software simulation of smart antennas mounted on base stations in a wireless communication system is described. We begin with the introduction of the smart antenna considered and its basic operation: the adaptive arrays based on a temporal reference. Next, the scheme of the simulated system is analysed, and in particular the characterization of the indoor mobile radio channel with ray launching techniques. Finally, we show some simulation results, making reference to the reduction of the uncorrelated multipath contributions, the quality improvement and the rejection of co-channel interference.
