Data Driven Modeling of Non Linear Microwave Devices

An inference based method for modeling complex non linear systems is presented that integrates current approaches to mod eling of microwave devices within a gen eralized non linear framework Familiar techniques for characterizing and emulat ing linear and non linear systems are em bedded in an automated weighting mech anism so that globally complex behavior is approximated by a number of simple lo cal models The framework handles non Gaussianity non stationarity and disconti nuity It o ers meaningful parameters such as linear lter coe cients or Volterra ex pansion coe cients as well as detailed error estimates
