摘    要:在已知台站布置的跳频系统中,针对邻频干扰对系统中断概率的影响,分析了接收端信干噪比(SINR)的分布函数,得到了以信道参数、干扰台站数和可用频点数为变量的中断概率公式。理论计算和仿真结果表明,信道参数、干扰台站数是影响中断概率的主要因素,可用频点数与中断概率有类反比的关系。该结果为跳频系统的性能分析和台站布置提供了指导。

关 键 词:跳频系统  邻频干扰  中断概率  分布函数

Abstract:Aiming at the influence of outage probability caused by adjacent frequency interference of the radio stations in frequency hopping(HF) system,this paper analyzes the probability distribution function(pdf) of the signal-to-interference-and-noise ratio(SINR) at the receiving end and obtains the formula of outage probability with the channel parameters,number of interferences and available frequency points. Theoretical analysis and simulation results show that the channel parameters,number of interferences are the main factors influencing the outage probability. The relationship between the outage probability and the available frequency points is inversely proportional likely. The result provides guidance for performance analysis and system planning of HF systems.
Keywords:frequency hopping system  adjacent frequency interference  outage probability  probability distribution function
