摘要
由于模数过渡期频谱资源紧张,在地面数字电视频率规划中大量使用了单频网的组网方式,单频网的优化方法被广泛关注和研究。本文运用遗传算法,通过调整单频网系统内各发射台站的位置来实现地面数字电视单频网系统的优化,以达到提高单频网优化效率、提升单频网覆盖效果的目的。
Due to the lackness of frequency resource in the transition period from analog to digital era, single frequency network （SFN） is widely used in DTMB frequency planning. SFN optimization is concerned comprehensively. This paper realizes SFN optimization by changing the position of transmitting station with genetic algorithm. Finally this paper achieves the purpose of SFN optimization and coverage promotion.
