  • ABSTRACT: In this paper comparative analysis is made for the required signal to noise ratios for the different modulation constellations QPSK, 16QAM and 64QAM for DVB-T, where BER=1*10 -7 is achieved. This guarantees quality transmission of the modulated data. Using the standard model for digital modulation 64QAM for DVB-T in MATLAB/Simulink, new models are created for QPSK и 16QAM. This allows for comparative analysis and evaluation of transfer speeds in different signal to noise ratios.
