Computer simulation of mobile communication systems operating in an urban area

In the present work analysis of correlation properties of single paths of multipath signal and its other parameters on spatial diversity antennas for mobile station moving with alternate speed (with acceleration) in an urban area by means of simulation are given. An investigation of fading envelope cross correlation in spaced antennas of one mobile station has been made. It is shown that normalized cross correlation function of fading envelope and phase has non exponential nature and decreases with reduction of mobile station acceleration. An analysis of influence of building configuration and mobile station position change in an urban area on mobile subscriber location error when multipath signal arrives from several directions is carried out. It is shown that location error decreases with reduction of average distance between scatterers and mobile station.
