摘要
结合使用Gilbert模型和Jakes改进模型,对无线移动信道模型进行仿真,准确地模拟了实际中的无线多径衰落信道。改进的信道模型中增加了突发错误状态,更加符合实际无线移动信道特征。仿真结果证明了丢包率与分组大小之间近似为线性关系,曲线的斜率随误比特率的增长呈线性增长模式。
This paper introduces the simulation on wireless mobile channel models by using Gilbert and the improved Jakes model. The outburst error state that added in the improved models accords with the characteristics of real wireless mobile channels. The result of the simulation proves that the relationship between packet loss rate and packet size is approximately linear, and further- more, the curve slope presents linearity relation with the variety of the bit error rates.
