Selection of optimal points for monitoring a single frequency network in digital terrestrial television of the Irkutsk region

Abstract

The article considers selecting points methodology for the main parameters monitoring of digital terrestrial television in densely populated areas of the Irkutsk region. Requirements for the choice of the measurement site have been developed. The measurements were carried out using a powerful broadcasting area of individual transceiver objects operating in a single frequency network. To carry out a research a control and measuring complex was created and a number of measurements were carried out in different areas of the Irkutsk region. During the experiment, the terrain relief, the zone of reliable reception, and the overlapping zones of signals from various stations of the single-frequency network were taken into account. The results of measuring the electromagnetic field strength, modulation error rates, bit error rates are presented in the paper. The methodology presented in the work allows you to identify errors timely and interference in a single-frequency network improving the reliability of the network and the quality of services provided.
