摘要
首先介绍了Link4A信号的特征,建立了各种干扰样式模型,并在非相干检测前提下分析了各种干扰样式的理论误码率,仿真了各种干扰样式对Link4A的干扰效能;其次,提出了可能影响干扰效能的因素,并仿真分析了各因素对误码率的影响。
This paper firstly introduces the characteristic of Link4A signal,builds the models of various jamming modes, and analyzes the theoretical error rate of various jamming modes on the base of non-coherent detection, simulates the jamming effectiveness of various jamming modes to Link4A;then puts forward some factors which may affect the jamming effectiveness,and simulates and analyzes the influence of various factors on the error rate.
