Digital video broadcasting-terrestrial (DVB-T) is a leading international standard established for the move from analogue to digital broadcasting basically via terrestrial networks. Within DVB-T, it is possible to carry defined data containers in addition to the audio and video in the MPEG-2 transport stream. These data containers can be used to realize new data services or to carry IP datagrams. Thus it enables large amounts of data to be delivered to a lot of users in mobile environment. A simulation-based approach for assessment of the DVB-T networks is done using OPNET software. This paper focuses on the generation and reception of a DVB-T OFDM signal in a physical channel that is simulated using Matlab and the results are analyzed. In an outlook, possibilities for future improvements are shown.
