ARTICLE ANNOTATION

quote
In the work there are researches of the ways to increase the noise immunity of DVB-T2 standard using the standardized characteristics of the systems, there is a comparative analysis of these parameters in DVB-T and DVB-T2 systems and the ways to increase the noise immunity of terrestrial digital television system. The dependencies of the bit error ratio (BER) on the signal/noise ratio were investigated and analyzed. The comparative analysis of data, parameters in DVB-T and DVB-T2 systems was carried out. There was made a comparison of "signal/noise" relations at the same transmission speeds and there were given technical data for transmission modes, allowing providing the maximum system capacity, which is achieved at the maximum FFT dimension, the highest modulation order and the minimum protective interval. Research results are given as: Bit error ratio dependence on signal/noise ratio, modulation parameters, TV signal transmission speed and normalized parameters of DVB-T and DVB-T2 systems. To study the parameters and characteristics of QPSK modulated signals the "Program for calculation of QPSK modulated signals time diagrams" in the Borland Delphi programming environment was developed.
