A METHOD OF MEASURING SPEED OF A MOBILE UNIT IN A WIRELESS COMMUNICATION SYSTEM

摘要

A method of measuring speed of a mobile unit for use in a wireless communication system (20). The method includes the steps of receiving a radio frequency (RF) signal from the mobile unit (202), measuring signal quality of the RF signal to produce a received quality signal (204), sampling the received quality signal during a first time period to produce a first group of samples (206), sampling the received quality signal during a second time period to produce a second group of samples (208), calculating a variation in signal quality of the RF signal in response to the first and second group of samples (210), and determining a speed measurement in response to the variation in signal quality (212).
