INVESTIGATION AND SIMULATION OF OPTIMAL NOISERESISTANT RECEPTION IN DVB-T2 STANDARD DIGITAL TELEVISION SYSTEM USING MATLAB/SIMULINK PROGRAM ENVIRONMENT

Abstract

In this work, the optimal noise-immune reception in a digital
television system of the DVB-T2 standard was investigated and modeled using the
Matlab/Simulink software environment. An analysis was made and the
requirements for normalized technical parameters that determine the quality and
noise immunity of signal reception in the DVB-T2 standard were investigated.
Various communication channels are modeled and investigated, such as: the
Gaussian, Rice and Rayleigh channel to determine and measure the signal-to-noise
ratio, the theoretical and practical influence of communication channels on noise
immunity. The results of researches on the dependence of the probability of a bit
error and the number of bits received with an error on Eb/N0, the spectrum of
QPSK signals and constellation diagrams are presented.
