Abstract: For use in or as part of a communications system benefiting from compensation for one or more non-idealities of components in the communications system, aspects of the invention are directed to providing compensation for such non-idealities. An example method which is applicable in a system that receives a pilot signal having an expected amplitude, includes determining a received amplitude for the received pilot signal using at least one of the components of the communications system, and using feedback indicative of a comparison of the determined received amplitude and the expected amplitude, compensating for a non-ideality of the component.
