    Abstract: PROBLEM TO BE SOLVED: To provide such a method and a device for estimating the speed of a mobile object in which the error tolerance is relatively small and which are not affected by the number of coefficients of channel impulse response in a radio communication system. SOLUTION: This method for estimating the speed of a mobile terminal (e.g. mobile telephone) communicating with a station in the radio communication system is provided. The speed estimating method includes a calculation (32) for normalization self-covariance of instantaneous power of a signal to be received by a terminal or station. It becomes possible to obtain results independent of the number of coefficients of channel impulse response, and the speed information having relatively small error limit can be acquired from the results.

    Abstract: The method of notching the transmission band of an analog signal to be transmitted and including sub-carriers to be modulated from digital modulation coefficients respectively associated to said sub-carriers, said method comprises providing (30) an initial digital signal from successive frequency-domain groups each containing said digital modulation coefficients respectively associated to said sub-carriers, filtering (31) said initial signal with a frequency resolution greater than the frequency resolution of said frequency-domain groups in order to remove frequencies corresponding to said sub-carriers to be removed and windowing (32) said filtered signal using a windowing mask (WMSK) having a representation in the frequency-domain including a main lobe and secondary lobes, the power spectrum of said lobes decreasing faster than the inverse of the frequency squared.
