Description

ABSTRACT

The article analyzes the main reasons for reducing reliability, channel violations during the transmission and reception of digital television signals. The main regularities of noise-resistant formation of quadrature-amplitude modulation are investigated. Mathematical models, vector diagrams of the QAM signal and the results of a theoretical study of the dependence of the bit error probability on Eb/N0, to ensure noise-immune reception of digital television signals.
