摘　　要：预测电波传播损耗是无线通信网络规划的重点,只有精心地设计与规划无线电路,才能保证通信质量。结合战术无线通信背景,对比分析了预测超短波电波传播损耗的多子模型算法,从相对余隙和传播距离两个参量对多子模型进行分类。在对算法的研究分析中,可在以电路余隙为判据的多子模型中使用以传播距离为判据的多子模型,从而完成算法的复合判决,提高算法的准确性。依据新的融合算法,以电波传播损耗的均方偏差为标准,经过实验,在一定条件下证明了该融合算法可以取得更好的精度。It is important for a plan of wireless communication network to predict propagation loss of radio wave.Because a good plan of wireless circuit can guarantee communication quality.Based on the background of tactical wireless communication,this paper compares and analyzes multi-model algorithm,used for predicting VHF propagation loss.And it classifies the multi-models from two parameters--relative propagation gap and propagation distance.In process of using the multi-model based on relative propagation gap,in which it can be found that the multi-model based on propagation distance can be used,completing compound decision rules of the algorithm to improve accuracy of the algorithm.According to the new fusion algorithm,taking mean square deviation of radio propagation loss as an evaluation standard,experiments prove that the fusion algorithm can achieve better results under some certain conditions.
