The Analysis of Overlapping Area of Digital Terrestrial Television Single Frequency Network Based on Discrete-Point Fitting Algorithm
For terrestrial digital television, the signal analysis of the overlapping coverage area of the single frequency network (hereinafter referred to as the overlapping area) is an important basis for improving the signal reception performance in this area. In this paper, the phenomenon and cause of "signal self-interference" in the overlapping area of single frequency network are analyzed, and the overlapping area under given signal parameters is accurately given by using the discrete point fitting algorithm. The feasibility and effectiveness of this method are verified by simulation experiments, and the expected effect is achieved.
