Abstract
U radu je opisan postupak sinteze pulsova za UWB-IR te pozadina načina rada takvog radija. Definirani su uvjeti koji moraju biti zadovoljeni za takav sustav te pravne regulative definirane FCC maskom. Razvijene su matlab funkcije za sintezu pulsa za UWB-IR bazirane na idealnim i realnim impulsnim odzivima različitih gaussovih monopulsova. Pokazano je kako odašiljački filtar ima smisla konstruirati za redove derivacije od četvrte pa na više, jer za manje redove signal ne upada u FCC masku te imamo potrebu za miješalom koje je skup i kompleksan element sustava. Objašnjeni su pojmovi vezani za sažimajuće očitavanje, uvjeti koje signal mora zadovoljiti da bi sažimajuće očitavanje bilo primjenjivo na njemu te sami način rada takvoga sustava. Navedeno je par primjera i aplikacija kojima je sažimajuće očitavanje od velikog interesa. Testirana je kvaliteta svih napravljenih odašiljačkih filtara izrađenih u radu praćenjem degradacije omjera signal/šum nakon izlaza iz akvizicijskog sustava sa sažimajućim očitavanjem u odnosu na izlaz iz kanala te računanjem spektralne učinkovitosti za svaki od filtara u odnosu na FCC masku.
Abstract (english)
In this work, pulse synthesis for UWB-IR and the theoretical background on how things work are described. The conditions that must be met for such a system and the legal regulations defined by the FCC mask are defined. Matlab pulse synthesis functions for UWB-IR based on the ideal and realistic impulse response of different gaussian monocycles are developed. It has been shown that the transmitter makes sense to construct for higher order derivatives of Gaussian monocycle, from 4th to higher, because lower order derivatives do not fill in the FCC mask. If we would like to make those lower derivatives contained in the FCC mask, a frequency mixer should be used, what makes the system too expensive and complex. Concepts related to compressive sensing, terms that the signal has to satisfy for compressive sensing to be applicable on it and the way the compressive sensing works are given. A number of examples and applications that are using compressive sensing are summarized. The quality of transmitting filters designed is shown in two ways, first one is the SNR degradation after acquisition system that is using compressive sensing in relative to the channel output and the second one is by computing the spectral efficiency for each filter designed in relation to the FCC mask.
