Research of path loss exponent and distance estimation based on Doppler effect and frequency diversity

With the need of localization based services increasing, many algorithms are proposed using distance between two points and path loss exponent of the environment. In this paper, we propose an algorithm using received signal strength, Doppler Effect and frequency diversity in vehicular networks. The algorithm can estimate the path loss exponent and distance dynamically in mobile communication environment. And the higher the relative speed of vehicles, the better performance of the propose technique. We evaluate the performance of the proposed algorithm in the simulation and discuss the corresponding results.
