| 摘 要： | 为了解决地面数字电视单频网选址陷入局部最优的问题,文章将模拟退火算法应用到地面数字电视单频网选址过程中,提出一种基于模拟退火的地面数字电视单频网选址算法。将模拟退火算法与地形因素相结合,优化了计算模拟退火算法接收较差站址选择配置概率的方法,从而可以根据地形状况来决定是否加快运算速度。基于专业软件NG_RadioPlan进行了二次开发,仿真结果表明,该算法能够有效地进行站址选择。

| Abstract: | In order to avoid local optimum site selection for the Single Frequency Network (SFN) of terrestrial digital television, this paper applies the simulated annealing algorithm in the selection process and proposes a simulated annealing-based site selection algorithm for the SFN. By combining this algorithm with the topographic factors, it optimizes the configuration probability in receiving poor site selections so that it is possible to decide whether or not it can accelerate the operation according to terrain conditions. Furthermore, it conducts a secondary development on the basis of the professional software NG_RadioPlan. Simulation results show that this algorithm can effectively carry out site selection. |
