摘　　要：针对短波的多信道通信中存在三阶互调干扰问题,为提高组织运用中管理效率,实现避免三阶互调干扰,论文设计了一种可行高效的频率分配算法。运用Matlab程序编写并计算出一个频谱利用率高,无三阶互调干扰的频率表。该算法简单有效地通过频率分配,能够较好地提高通信质量。Multi-channel communications for shortwave third-order intermodulation interference problems exist.To improve the efficiency of organizations in the management,avoid third-order intermodulation interference,a feasible and efficient frequency allocation algorithm is designed.Matlab programming is used to calculate a high spectrum efficiency,no third-order intermodulation interference frequency table.The algorithm is simple and effective by the frequency distribution to improve the communication quality.
