1. for the treatment of the method for sequence of pilot symbols, for estimating the transfer function of transmission channel, at least one radioCommunicator communicates by described channel and remote base station, and described remote base station is logical to described radio regularlyT unit sends a reference model, and described reference model has at least by the time interval between two frequency pilot signs and twoStructure in the T/F space that frequency interval between frequency pilot sign defines,It is characterized in that comprising the following steps:

  • Measurement belongs at least one transmission channel spy of the group that comprises channel maximum doppler frequency and/or maximum delay spreadLevy;

    In communication period, by change the value in the time interval between described two frequency pilot signs and/or two frequency pilot signs itBetween the value of frequency interval, change the structure of described reference model according to transmission channel characteristics described at least one;

    Described at least one, in radio communication device, extract described sequence of pilot symbols.
