Research on Receiving Performance Optimization of Overlapping Coverage Area in Terrestrial Digital Television Single Frequency Networks under Complex Terrain
The reception performance of the overlapping coverage area is the key technology in the single frequency terrestrial digital television network.In the area of complex terrain,how to master and deal with the factors that may affect the reception performance in the overlapped coverage area of the single frequency terrestrial digital television network is a practical challenge faced by the single frequency network.In view of this,on the basis of introducing the reception performance of the overlapping coverage area of the terrestrial digital television single frequency network,the factors affecting the reception performance of the overlapping coverage area of the terrestrial digital television single frequency network under complex terrain conditions are summarized,including topography,transmitter layout,signal propagation path and multipath effect,and then the measures to ensure the reception performance are proposed.It provides a reference for the technical scheme of single frequency network under complex terrain.
