Title: Self-calibrating multi-port circuit and method

Abstract: The invention provides a type-based method to compensate for distortions in circuits operating on a plurality of input modulated signals to form one or more output modulated signals. Steps of the method include low-rate sampling of the output signal to obtain a statistical characteristics thereof, and adjusting parameters of the circuit to introduce a controlled degree of cross-coupling between the signals until the statistical characteristics of the output signal approximates a reference characteristics defined by the used modulation formats. Another aspect of the invention provides a self-calibrating multi-port circuit implementing the method.
