Evaluation of efficiency of fighting with interference distortion in Single-Frequency Networks of TV broadcasting

Abstract

This research shows the interference occurrence in Single-Frequency Networks for Digital Television broadcasting which influence on the quality of receiving in the overlapping service zones of transmitters. The article contains qualitative and quantitative evaluation of the compensation effectiveness of the interference distortion in the receiver's demodulator. The results were obtained using CADs VSS Applied Wave Research and ADS Agilent Technologies and allow us to evaluate the limiting value of signal/echo-signal ratio for a given signal-noise ratio which provide network operability.
