/Arbeiten/uploaded/276DVB-T3.jpgThe Digital Video Broadcasting-Terrestrial (DVB-T) is a standard for transferring multiplexed audio-visual data from the base station to the end user. The DVB-T uses Orthogonal Frequency Division Multiplexing to transfer its data and realizes QPSK, 16-QAM and 64-QAM modulation schemes. At CEL, a software defined radio platform in the form of USRP is available. The radio hardware can be configured through a software interface to realize different communication standards. All the baseband signal processing is implemented using GNU Radio over the computer. The GNU Radio contains in-build generic modules like modulation, OFDM blocks, etc, that can be used for implementing the DVB-T transmitter chain.



The tasks for the thesis is grouped under the following work packages:
- Understanding the DVB-T standard.
- Realization of the DVB-T transmitter over the USRP.
- Live demonstration: Transmission of the recorded audio-visual data using the DVB-T transmitter followed by its reception over a generic DVB-T receiver (available at CEL).
