Abstract

Ovaj rad opisuje implementaciju digitalnog radio prijamnika za prijam DAB+ signala. Prvi dio rada daje opće informacije o DAB+ standardu i tehničke značajke emitiranog signala. Opisan je princip snimanja kompleksne ovojnice DAB+ signala s lokalnog odašiljača i njen prijenos na osobno računalo. U tu svrhu koristi se akvizicijski sustav RTL SDR i razvojna platforma koju čine razvojni sustav Xilinx ZC706 i AD-FMCOMMS5 platforma. U sklopu rada proučen je i dokumentiran način pakiranja informacija unutar DAB+ prijenosnog okvira kao i dekodiranje zvučnog zapisa koji se prenosi. Unutarnji prijamnik, vanjski prijamnik i dekoder implementirani su unutar programskog okruženja Matlab. Uhodane su i isprobane dvije implementacije AAC dekodera. Na kraju su dane upute za testiranje i verifikaciju implementiranog sustava.

Abstract (english)

This thesis studies the implementation of DAB+ digital receiver. In the first part of the thesis, general features of DAB+ standard and the parameters of transmission signal are given. The second part describes the principles of capturing a complex envelope of DAB+ signal and transferring the captured data to the computer. This is achieved by using RTL-SDR system or ZC706 development kit connected to AD-FMCOMMS5 platform. Packing the information in DAB+ logical frames, along with audio encoding have been studied and documented. The inner receiver, the outer receiver, and the audio decoder are all implemented in Matlab. Two implementations of AAC decoder were analyzed and tested. The last part contains the guidelines for testing and verifying the implemented receiver.
