Sažetak predavanja:

Windowing is a common method in signal analysis and in digital and spatial filter design. In many cases, adjustable windows are preferable since they offer a tradeoff between requirements, usually sidelobe level and mainlobe width. In this talk, we present a straightforward method for the design of windows with prescribed sidelobe level or mainlobe width. The method is based on the transform of a given window into the polynomial, thus enabling the use of polynomial approximation in the window design. Consequently, the method introduces an additional degree of freedom into the design process. The features of the method are illustrated with the design of linear antenna arrays having low dynamic range ratio and high beam efficiency. In particular, the adjustment of Taylor-Kaiser arrays, the design of arrays with minimum dynamic range ratio based on the transformed Gaussian windows, and the combined array design incorporating rectangular and Gaussian window.

 

Životopis predavača:

Marko Matijascic received the Master degree in Electrical engineering and information technology from the University of Zagreb Faculty of Electrical Engineering and Computing, Zagreb, Croatia, in 2018. In 2019 he enrolled in the Doctoral study at the same faculty. After the Master study, he has been employed in the Research and Development Centre of Ericsson Nikola Tesla d.d. in Zagreb, where he works as Software/Hardware Developer in the Radio Development Unit. In the unit, he is also a member of the Scientific Radio group in which he participates in the project "Efficient Signal Processing Systems for Software Defined Radio" funded by Croatian Science Foundation. His research interests are in the field of software defined radio, signal processing for communications, analog and digital beamforming, and antenna array design. He is a member of IEEE societies on Signal Processing, Antennas and Propagation, and Circuits and Systems.
