Digital terrestrial television broadcasting error rate measurement

This paper deals with a measurement of bit error rates in the DVB - T transmission system. Both non- hierarchical and hierarchical modulations are examined as well as basic transmission channel models (Gaussian, Rice and Rayleigh). Measured bit error rate before Viterbi error correction (channel error rate) and after Viterbi error correction, with varying C/N ratio, are graphically expressed and compared to the values mentioned in the DVB - T specification. A broadcast test system "SFU" developed by Rohde& Schwarz and a test receiver "MSK 33" by Kathrein were used for the measurement. Finally, obtained results are evaluated and discussed with the theory.
