1. A method of estimating the speed of a mobile station in a MIMO, SIMO or MISO wireless communication system, the method comprising:

  • concurrently receiving a plurality of radio signals;

    deriving a value for the derivative of the envelope of the path transfer function for each radio signal;

    computing an estimate of the Doppler spread of each of said radio signals from said derivative values; and

    deriving a value for the speed of said mobile station from said Doppler spread estimates.
