A moving speed detecting method of a mobile radio terminal which makes communication
with a base station outputting a pilot signal includes a step of predicting phases
and amplitudes of the pilot signal from the base station by using a plurality of
prediction methods having different characteristics. A calculating step calculates
errors for the prediction results, which are obtained for respective prediction
methods in the prediction step, and a prediction error comparing step compares
the prediction errors with respect to each of the prediction methods, which are
calculated by the calculating step, to detect a moving speed of the mobile radio terminal.
