Abstract

An application of continuous-time system identification to the modeling of a power amplifier used in mobile communication is proposed. Generally, electronic components modeling uses discrete-time black-box models. In order to keep physical knowledge and easy interpretation of estimated model, a continuous-time transfer function model is chosen to represent amplifier transmittance. Hence, parameter estimation is performed by the reinitialized partial moments method. This estimation method has been chosen because of its insensitivity to initial conditions and rough system a priori knowledge. Then, power amplifier continuous-time model allows immediate physical interpretation to the electronics engineer.
