A process for estimating a speed of movement of a mobile terminal
operating in a wireless communication system and communicating with a
base station via a transmission channel includes estimating fading of the
transmission channel, and performing an autocorrelation on the fading for
providing a first autocorrelation result. Reference autocorrelation
results are calculated for predetermined values of speed of movement of
the mobile terminal, with the calculating being based upon a known
autocorrelation function performed on the fading. The process further
includes comparing the first autocorrelation result to the various
reference autocorrelation results, and estimating the speed of movement
of the mobile terminal based upon the comparison.
