Abstract

U ovom diplomskom radu opisana je teorijska problematika sažimajućeg očitavanja te je prikazan razvoj cjelovitog sustava za akviziciju i rekonstrukciju signala temeljenog na sažimajućem očitavanju. Naglašen je pristup razvoju rekonstrukcijskog algoritma koji se izvodi na razvojnom sustavu ZedBoard Zynq-7000 ARM/FPGA SoC. U radu je opisana akvizicijska pločica koja se sastoji od šest paralelnih kanala te razvijeni digitalni dizajn za upravljanje istom. Također razvijen je i privremeni sustav s... More emuliranim akvizicijskim sklopovljem u svrhu razvoja rekonstrukcijskog algoritma koji se sastoji od STM32F4 mikrokontrolera baziranom na ARM Cortex-M4 procesoru povezanog sa ZedBoardom pomoću SPI sučelja kojim se šalju mjerni podaci prema ZedBoardu.

Abstract (english)

In this master thesis the theoretical side of compressive sensing is described. Furthermore, development of a compressive sensing system for signal acquisition and reconstruction is described. Development of the reconstruction algorithm which is executed on the ZedBoard Zynq-7000 ARM/FPGA SoC development board is highlighted. A signal acquisition board which consists of six parallel channels is described alongside the developed digital design which controls the acquisition board. A... More temporary system with emulated signal acquisition hardware was developed for the testing purposes of the reconstruction algorithm which consisted of a STM32F4 microcontroler based on an ARM Cortex-M4 processor connected to the ZedBoard over the SPI interface which was used to transmit measurement data to the ZedBoard.
