Abstract

This paper presents a method to measure and predict the reception quality of the digital terrestrial/television multimedia broadcasting (DTMB) system in a single frequency network (SFN) environment. Measurement of the signal-to-noise ratio (SNR) threshold at several market commercial receivers was carried out in the laboratory. After analyzing the channel capacity loss produced by the multiple transmitter reception, a prediction model of SNR threshold is presented. Simulation results are also performed to verify the accuracy of the prediction method. This model and method could be adopted for SFN planning to ensure a good service quality in the SFN environment.
