Abstract :
This paper describes an experiment to extract the dynamic nonlinear model of a millimeter-wave communication system with ultra-wideband signal. The device under test consists of a pair of 60 GHz RF transmitter and receiver and the wireless channel between them. Input and output signals used to extract the behavioral model are the baseband signals before imported to the transmitter and after demodulated by the receiver, respectively. The experiment is based on QPSK modulated signals with 200MHz bandwidth and 4.6dB peak-to-average power ratio (PAPR). With a Joint memory polynomials (JMPs) model, the normalized mean square error (NMSE) between the simulation and measurement output reached -22.4dB. To the authors´ best knowledge, this is the first report on a behavioral model with such wideband signal.
