1. one kind is the method that produces prewhitening filter from the signal of communication of wireless communications network base station emission, and this method comprises:

  • Estimate that total base station transmitting power and presence of intercell interference add the ratio of the power spectral density of noise;

    Add that based on total base station transmitting power and presence of intercell interference the estimation of the power spectral density of noise recently calculates scale factor;

    AndBe identified for the prewhitening filter of albefaction signal of communication as the function of the frequency response of this scale factor, the frequency response relevant and the propagation channel by its receiving communication signal with the transmitted pulse shaping filter used in the base station.
