| 摘 要： | 跳频通信网中用户间跳频码碰撞会引起相互干扰,可采用独立碰撞模型和4碰撞态的马尔可夫模型加以研究.本文提出设定4种碰撞态下各有不同的误码和删除概率,可用来调整复杂信道模型参数的影响.我们注意到在用户数稳定时,4碰撞态的马尔可夫过程是平稳的,建议工程计算中采用可简化计算的独立碰撞模型. |

| 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. |
| Keywords: | Random sequences Frequency-hopping Error code probability |
