| 摘 要： | 在陆基车载通信系统中，多部跳频电台间存在着严重的共址干扰问题。针对车载多部VHF跳频电台存在的共址干扰问题，在确定频段划分工作模式和共址干扰产生条件的前提下，基于共址干扰发生概率的分析，建立了VHF跳频系统频率表分配优化模型。采用大量随机约束样本试探方法和多目标遗传算法，求解得出了满足干扰概率容限的共址电台数量及其跳频频率表分配集合，并给出了该模型的实例仿真与验证结果。

| Abstract: | VHF Frequency hopping radios located together on a vehicle may cause serious interference, which is called co-site interference. According with this problem, the frequency-distribution mode and the precondition of causing co-site interference are determined. Based on the analysis of co-site interference probabilities, a multi-objective optimization model is established to optimize the frequency-distribution for VHF frequency- hopping radios. Optimized result is achieved by using the multi-objective genetic algorithm and heuristic method based on a mass of random restriction samples. Simulation and verification results are given. |
