Abstract :
A sophisticated simulation package for automatic vehicle monitoring (AVM) systems using a pulse ranging technique has been developed. Using a multipath propagation database, location-error statistics have been obtained for mobile units operating in areas with various degrees of urbanization. The effect of the number and relative position of sensors on location-error statistics has been studied in detail. The performance of various linear and nonlinear optimization techniques has been tested by computer simulation. Application of the package to locating vehicles and portables in digital cellular radiotelephone systems for the purpose of channel assignment and handoff supervision has been studied. It is shown that such techniques are quite feasible even in the worst multipath propagation conditions
