DETERMINATION OF THRESHOLD PARAMETERS FOR RELIABLE RECEPTION (MERmin, SNRmin, Pth) OF DVB-T2 SIGNALS IN THE MOUNTAINOUS REGIONS OF TASHKENT PROVINCE

Abstract

Digital terrestrial television broadcasting of the DVB-T2 standard is the

basis of the modern broadcast television system, providing high spectral efficiency,

noise immunity, and the ability to transmit high-definition digital content.

However, the reliability of DVB-T2 signal reception largely depends on the

conditions of radio wave propagation, which in mountainous areas are

characterized by pronounced territorial heterogeneity, shielding relief, multi-beam

propagation, and significant attenuation levels.
