摘要
以广电总局推荐的地面数字电视工作模式5为理论基础,首先理论分析了影响地面数字单频网内产生同频干扰现象的技术参数;其次通过仿真规划软件调整相关技术参数,同时观察单频网内同频干扰区域分布情况并总结规律;最后根据已知技术参数对干扰区域的影响,尝试提出消除覆盖区域内同频干扰现象的优化方案,并通过仿真规划软件进行模拟。
Based on SARFT recommendation of DTMB work mode 5, firstly, the technical parameters which can cause interference are analyzed. Secondly, adjust related technical parameters through simulation planning software, and observe the interference dis- tribution area and summarize the rule. Finaly, according the known technical parameters of the interference, the eliminate interfer- ence optimization method is put forward, and simulate through the software.
