1. In a communications system, a method comprising the steps of:

  • receiving a signal transmitted over a communications channel;

    measuring an estimate of an energy value and an interference value of the received signal;

    determining a measured signal-to-interference ratio (SIR) value using the measured energy value and the measured interference value;

    determining that the measured SIR value exceeds an SIR saturation threshold; and

    thereafter, correcting the measured SIR value for nonlinearity to obtain a corrected SIR value.
