1. A method of reducing a peak envelope power of a linear power amplifier amplifying a plurality of carriers of a corresponding plurality of channels, such method comprising the steps of:

  • measuring the peak envelope power of a composite of at least two of the carriers;

    measuring a channel activity level of one of the at least two carriers; and

    , when the measured peak envelope power exceeds a first threshold, changing a parameter of one of the at least two carriers when the measured channel activity level exceeds a second threshold.
