Abstract
A speed estimation apparatus detects the change of a transmission power control command transmitted from a receiving station and estimates the moving speed of the receiving station in mobile communications of a spread spectrum system. The speed estimation apparatus also generates a desired signal power by extracting a desired signal from received signals and estimates the moving speed of a corresponding transmitting station using the desired signal power.
