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...
A novel low cost radiated emission measurement system by using current probe has been proposed in this paper. Compared with conventional anechoic chamber measurement method, this new method could reduce test cost and save developing time efficiently. In order to improve the accuracy, a transfer function has been built for mapping the relationship between current probe method and anechoic chamber method...
Space-alternating generalized expectation-maximization (SAGE) algorithm is proposed to compute the jointly maximum-likelihood estimate of the relative delay, incidence azimuth, and complex amplitude, which are considered the character parameters of impinging waves in indoor radio environments. The maximization processes of SAGE algorithm can be separated into several individual procedures which can...
