Matlab simulation of the DVB-T transmission

This paper deals with a Matlab application currently being developed to simulate DVB-T transmission in various transmission channels. The application structure and its functions are described. The aim was to implement all the functional blocks as specified in the DVB-T specification. Dependence of BER on C/N ratio as a result of the simulation in the Gaussian channel is graphically expressed and compared to the results of the laboratory measurement. The reference measurement was performed using Rohde & Schwarz SFU (broadcast test system) unit as the transmitter and Kathrein MSK-33 DVB-T test receiver. Finally, obtained results are discussed.
