1. A method for operating a radio frequency RF receiver, comprising:

  • during operation of the RF receiver, periodically determining existing RF receiver operational conditions, by separately measuring levels of signal interference associated with blocking and intermodulation of a received signal;

    determining RF receiver performance requirements based at least in part on the determined existing RF receiver operational conditions, taking into consideration the measured levels of signal interference associated with blocking and intermodulation; and

    allocating power consumption between RF receiver functional blocks in accordance with the determined RF receiver performance requirements using a behavior model of at least one of the RF receiver as a whole and individual functional blocks of the RF receiver, wherein the behavior model maps RF receiver performance requirements onto power consumption allocation.
