Multiplierless multirate filters based on amplitude sharpening and compensation
Predavanje je otvoreno za sve zainteresirane, a posebno pozivamo studente.
The simplest multiplierless multirate filter is the cascaded-integrator-comb (CIC) filter. However, in processing of wideband signals, the CIC filter is often incapable of meeting the requirement for high folding-band attenuations. To improve the CIC-filter folding-band response, various structures have been developed. An efficient structure arises from the polynomial sharpening of the folding-band response. This structure implements so called sharpened CIC (SCIC) filter. However, the amplitude response of SCIC filter has a high pass-band droop, which is intolerable in many applications. The droop can be reduced by connecting a linear-phase finite-impulse-response filter called compensator in cascade with the SCIC filter. Since the original CIC filters are multiplierless, sharpened-CIC filters and compensators with multiplierless structures are preferable. In their design, maximally flat and minimax approximations over the sum-of-powers of-two coefficient space are convenient.
Aljoša Dudarin received the Master degree in Electrical engineering and information technology from the University of Zagreb Faculty of Electrical Engineering and Computing, Zagreb, Croatia, in 2011. After the Master study, he enrolled in the Doctoral study at the same faculty. Currently, he is finishing the PhD thesis in the field of digital signal processing and filter design. In 2013, he was employed as a Software Engineer at Xylon - an electronics company focused on FPGA IP core designs. Since 2016 he works as a Software Developer in Ericsson Nikola Tesla d.d. Research and Development Centre, Radio Development Unit, in Zagreb. In the unit, he is a member of the Scientific Radio group, where he participates in the research activities of the project Improvements for LTE Radio Access Equipment (ILTERA) - an educational and research collaboration project between Ericsson Nikola Tesla d.d. and the Department of Electronic Systems and Information Processing of the Faculty of Electrical Engineering and Computing, University of Zagreb.
