基于云模型的跳频无线通信设备抗干扰能力评估方法

评估的置信度是当前无线通信设备抗干扰能力评估工作的瓶颈,其难点在于评估中的模糊性和对主观经验的依赖性。针对该难点,提出了一种基于云模型的跳频无线通信设备抗干扰能力评估方法。首先构造了针对该评估对象的指标体系;其次借用云模型深入分析了评估中的模糊信息及主观因素,并在此基础上提出了置信度计算方法;最后,对算例进行评估和仿真,验证了方法的可行性。该方法主要优势在于既减少了主观成分,提高了评估的科学性和客观性,又较大程度地挖掘了评估中的模糊信息,给出置信度算法,从而反映评估结果的可信性,并为如何提高评估置信度提供了参考方向。

A cloud model-based method for evaluating anti-jamming capacity of wireless frequency hopping communication equipment

The study of confidence is a bottleneck for capacity evaluation because of the fuzzy character and subjective experience.In light of difficulties mentioned,this paper proposes a method for evaluating anti-jamming capacity of wireless frequency hopping(FH) communication equipment.In this method,subjectivity and fuzzy information is analyzed deeply on the basis of cloud model,and the equation for calculating confidence is proposed.Finally,the results of evaluation and confidence calculated for illustrative examples verify the feasibility of this method.This method has two main advantages.Firstly,it enhances the objectivity and rationality in indices quantization.Secondly,the dug fuzzy information and quantitative results of confidence equation reflect the accuracy and confidence of evaluation.It also provides the reference direction for improving confidence.
