ABSTRACT:
System and method for processing signals are disclosed. The method may include converting, in an RF receiver, one or more analog samples, which are selected from one of a plurality of output paths of the RF receiver, to one or more digital samples. A digital feedback value may be generated based on an average of the one or more converted digital samples. A scaled version of the generated digital feedback value may be converted to an analog value. The converted analog value may be fed back to one or more of a plurality of input paths of the RF receiver. The one or more analog samples may be selected from among a plurality of output analog samples from the plurality of output paths of the RF receiver.
