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.
