摘要
在网络转网和切换中,常会出现不稳定网络跳变信号,其以单频脉冲的形式造成网络波动,影响网络稳定与安全。对该类单频脉冲包络瞬时值有效统计,可以采用脉冲抵消方法抑制波动,提高网络性能。提出一种基于单元散射混响统计学模型的不稳定网络跳变单频脉冲包络瞬时值统计方法。构建网络跳变单频脉冲混响统计模型,进行脉冲信号混响建模,得到混响信号在网络组网及不稳定跳变中产生的脉冲响应。采用单元散射混响统计学方法对传统的包络瞬时值统计算法进行改进。研究结果表明,采用该算法,能有效统计不稳定网络跳变单频脉冲包络的瞬时值,统计结果准确,有效反应包络变化,为下一步采用脉冲抵消方法抑制波动奠定基础,提高网络性能。
In the process of network switching, it often appears unstable network hop signal, the single frequency pulse formnetwork fluctuation, network stability and security is affected. The single frequency pulse envelope instantaneous effectivestatistics is needed, it can be used to suppress the fluctuation pulse cancellation method, and improve the performance ofnetwork. A reverberation statistical model of unstable network is proposed based on jump single frequency pulse envelopeinstantaneous statistical method. Construction of network hop reverberation statistical model of single frequency pulse istaken, pulse signal reverberation modeling is obtained, and then the impulse response of reverberation signal generated inthe network and unstable jump. The unit reverberation statistics method is improved on the traditional values of the instan-taneous envelope statistics algorithm. The results show that the instantaneous pulse envelope values can be effectively com-puted for unstable network, statistical results are accurate, it can effective responses envelope change, and it can improvethe performance of network.
