DVB-T and DVB-T2 performance in fixed terrestrial TV channels

This paper deals with the DVB-T (Digital Video Broadcasting-Terrestrial) and DVB-T2 (DVB-2nd Generation Terrestrial) standards and their transmission performance in fixed TV channels. For the analysis and simulation of performance of both standards, classical Ricean and Rayleigh multipath fading channels with 20 independent paths were used. Simulation results of the BER (Bit Error Ratio) before and after FEC (Forward Error Correction) decoding were evaluated and compared for DVB-T and DVB-T2 standards. Dependences of MER (Modulation Error Ratio) on C/N (Carrier-to-Noise Ratio) were also obtained for both standards. Moreover, optimal configuration of the new DVB-T2 system for broadcasting of HDTV (High Definition Television) services was explored. Appropriate applications for these simulations were developed in MATLAB. Finally, achieved results are evaluated and clearly discussed.
