1. In a radio communications system, said system including multiple antennae for receiving signals and a control processor for identifying said antennae and processing said signals, and in which the typical duration of fadeouts in said system is in the magnitude of seconds, a method of assigning an antenna to receive a signal comprising the steps of:

  • measuring a parameter of the signal representative of signal quality;

    storing a simulation model for said measured parameter in said control processor;

    predicting the value of said measured parameter for subsequent periods of operation from the measured parameter, based on said model;

    setting a value for said parameter at which antenna selection should be made;

    comparing the predicted value to the set value; and

    assigning said signal to an antenna based on the difference between said predicted value and said set value.
