With fractional Gauss process, we analysis the estimation of autocorrelation and obtain an evaluating formula, in which the relation of the accuracy of estimated autocorrelation, sampled data length and Hurst parameter is accurately described.

• 我们以分形高斯过程为模型讨论了自相似网络通信量的自相关估计问题,从而得到了一个快速估计通信量自相关值的公式。 该公式较精确的描述了自相关估计精度、样本数据长度以及Hurst参数之间的关系。
