Performance Analysis of User's Interference in the Digital Frequency-Hopping of Communication Net

  • 摘要: 跳頻通信網(wǎng)中用戶間跳頻碼碰撞會(huì)引起相互干擾,可采用獨(dú)立碰撞模型和4碰撞態(tài)的馬爾可夫模型加以研究。本文提出設(shè)定4種碰撞態(tài)下各有不同的誤碼和刪除概率,可用來調(diào)整復(fù)雜信道模型參數(shù)的影響。我們注意到在用戶數(shù)穩(wěn)定時(shí),4碰撞態(tài)的馬爾可夫過程是平穩(wěn)的,建議工程計(jì)算中采用可簡(jiǎn)化計(jì)算的獨(dú)立碰撞模型。
    Abstract: User s interference in the frequency-hopping of communication net can be analyzed using the independent hit model or the Marcov modei with four hit states. In this paper, it is proposed that the error probabilities and erasure probabilities can be defined respectively in four hit states to adjust parameter effects of a complicated channel modei. The attention is payed to stabilizing the Marcov process with four hit states in fixed user s numbers, so it is suggested that the independent hit model can be used in engineering as to simplify the computation.
