Abstract
A receiver compensation method comprising receiving a radio frequency signal, amplifying the radio frequency signal, thereby producing an amplified signal, compensating the amplified signal, thereby producing a compensated signal, and mixing the compensated signal, thereby producing a mixed compensated signal, wherein the mixed compensated signal has a first gain difference between a positive differential from a center frequency and a negative differential from the center frequency and wherein the first gain differential is smaller than a second gain differential that would be obtained by mixing the amplified signal without compensating the amplified signal.
