Studies of pulse waveforms for UWB communications by ZHAO Jun-xi

“…The problem of designing pulse waveforms for UWB communications was investigated.A method of constructing pulse waveforms was proposed by optimally combining different Gaussian functions,and a simple pulse waveform with some desired properties was constructed by the method.Based on the ideal of filtering,a new approach to designing more flexible pulse waveforms for UWB communications was presented.Several numerical experiments were given to demonstrate the efficiency of this method.…”

Linear Active Disturbance Rejection Control-Based Voltage Controller for Buck and Boost DC/DC Converters in DC Distribution Grids by Asimenia Korompili, Oemer Ekin, Marija Stevic, Veit Hagenmeyer, Antonello Monti

“…The formulation of the proposed L-ADRC model in the non-canonical form facilitates the employment of model-based estimation and feedback control methods, whose performance is determined through the design of several parameters. This provides more degrees-of-freedom in the design of the voltage controller, beyond the design of the common L-ADRC formulation based on the bandwidth of the linear extended state observer and the scaling factor of a proportional error feedback controller. …”
