English abstract:
This research is about black-box modelling of a microwave Power Amplifier (PA) and its performance in the almost linear and compression operation modes. An in-band quasi-white noise complex-valued signal is used as input for the identification procedure. a segment of the input-output measurement data is processed to generate an initial model. The model is cross-validated with the entire measurement signal. The first order Volterra kernael is extracted in order to obtain an estimation of the amplifierīs memory. A new model is generated and possible performance improvements are studied. The result of this process is a suitable block-structure for the final amplifier model. this resulting model can be used for simulation of linearization systems or even in further identification processes.
