    摘要:

    跳频通信具有良好的抗干扰能力,但多通道转信系统工作于跳频模式时极易产生互调干扰。对跳频通信系统抑制互调干扰的频率分配方法进行了研究,使用模拟退火算法进行优化计算。在详细分析了跳频系统频率分配的约束条件基础上,对利用SA算法进行频率分配所使用的目标函数进行了改进,不完全以违约概率作为约束权值,而是结合多通道转信系统特点,根据约束重要性对其进行调整,在优化目标中加强了对互调干扰约束的关注,得到了较好的频率分配方案。

    Abstract:

    The frequency-hopping (FH) communication system has a good capability of anti-jamming. It’s easy to produce the intermodulation interference when multi-channel relay system working at FH mode. Through the use of simulated annealing algorithm for optimization, frequency assignment method for restraining the intermodulation interference of frequency-hopping (FH) communication system has been studied. By analyzing constraints of frequency assignment of frequency-hopping system, objective functions in the previous use of SA algorithm for frequency assignment have been improved. Not taking completely the probability of default as constraint weights, but strengthening the concern of intermodulation interference constraints, combined with the application background of this article, a quite good method of the frequency assignment has been received.
