Software Receiver Implementation

چکیده
Preface Wireless standards are subject to rapid development and frequent changes, making old hardware obsolete at a high rate. On the other hand, the constantly increasing computational power of general purpose computers allows developers to move functionality away from hardware and specialized processors, to high-level software running on arbitrary general purpose processors. This leads to the idea of software defined radios, where as much of the signal processing as possible is done in software. While this idea is not new, CPUs have only recently become fast enough for practical implementations of wireless standards in software. This semester thesis investigates the possibility of implementing a receiver for the Digital Audio Broadcasting (DAB) standard [1] in software, by using the GNU Radio toolkit – a free open-source framework for the creation of software defined radios.
