The invention provides a method of detecting high-mobility state of mobile terminal, comprising steps of: estimating a channel impulse response (CIR) based on received signal samples; performing channel equalization based on said received signal samples and the estimated channel impulse response; computing at least one characteristic value for a particular region of a relevant time slot based on the equalized signal samples; and deciding if said at least one characteristic value satisfies a predetermined condition that mobile terminal is in high-mobility state. The invention also provides a corresponding apparatus comprising: a channel estimator; a channel equalizer; computing means for computing at least one characteristic value for a particular region of a relevant time slot based on the equalized signal samples; and deciding means for deciding if said at least one characteristic value satisfies a predetermined condition of mobile terminal being in high-mobility state. |
