Abstract :
A method for locating mobile stations in a cellular telephone system is analyzed. This method uses hyperbolic multilateration of direct sequence radio signals that are transmitted by the mobile after it has been polled. The channel that would be necessary for the radiolocation signal could be created by reusing an entire 10-MHz mobile radio bandwidth. A direct-sequence locating system has been modeled and simulated using a multipath database for a dense urban environment. Location error statistics and statistics on locating mobiles in a cellular grid are presented
