Abstract
A gain compensation loop suitable for a quadrature receiver comprises a signal strength comparator having in-phase and quadrature signals fed to respective inputs of the signal strength comparator. The signal strength comparator outputs a signal which represents the difference in strength between the in-phase and quadrature signals. The signal output from the signal strength comparator is input to a gain adjuster which adjusts the gain of the in-phase or quadrature signal in accordance with the signal from the signal strength comparator to bring the in-phase and quadrature signals towards the same strength.
