ABSTRACT: The basic composition and working principle
of wireless collision avoidance and early warning system based on spread
spectrum ranging which is used in urban mass transit is introduced in this
paper. Some performance indicators such as maximum measured distance and range
errors are theoretically analyzed and numerically calculated. According to the
characteristics of the urban mass transit, the applicability of the system is
evaluated.
