摘要
对地面数字电视和CMMB单频网组网的同频干扰问题进行了详细研究,从理论上分析了来自不同发射点的信号场强和延时对单频网同步区域的影响,并找出了解决方案。最后给出了单频网实际组网同频干扰试算结果。
In this article, the co-channel interference of DTI＇B SFN and CMMB SFN is studied in details. Then, the influence of signals from different transmitters in field strength and time delay are theoretically analyzed, and the solution is presented. Finally, the simulation results of actual SFN co-channel interference are also presented.
