<p>A method and apparatus for approximating the doppler frequency of a mobile station (M1-M9) by examining the signal between the mobile station (M1-M9) and a base station (B1-B10). Several channel estimates (hj(n)) are calculated at different intervals (t1, t2) for the signal between the mobile station (M1-M9) and the base station (B1-B10). The difference (Vj(n)) between these channels estimates (hj(n)) is used to determine the approximate doppler frequency of the mobile station (M1-M9). A cellular mobile radio system can use the doppler frequency of the mobile station (M1-M9) to prioritize a handoff queue or to select an appropriate detecting algorithm for detecting data in a received signal (r(t)).</p> |
