摘要
抗干扰能力的研究始终是跳频通信系统中的关键问题。为了有效衡量常见干扰策略对于FH/BFSK系统的影响,首先指出干扰跳频系统的基本思路和评估标准。以不同的干扰策略为标准,划分常见的干扰类型。分别论证其基本原理、干扰效果和应用环境。基于FH/BFSK系统,计算不同类型干扰策略下的比特误码率。搭建系统的Matlab/Simulink模型,得到典型干扰的参数对误比特率的影响结果。为跳频通信的抗干扰研究提供了评估依据和仿真参考。
Antijamming capability is a key index in frequency-hopping system.In order to efficiently assess the impact of common interference strategies on FH/BFSK systems,the basic ideas and evaluation standards of FH system are firstly indicated in this paper.With interference strategies as evaluation standards,common interferences are classified into certain types.The fundamentals,interference effects and application environments are demonstrated respectively in this paper.Based on FH/BFSK system,the BER performance under different interference strategies is calculated.The Matlab/Simulink model is constructed to analyze the influence of typical interferences parameters on BER.It gives a good assessment and simulation reference to research the frequency-hopping system.
