我们考虑瑞利模型 [Foschini 和 Gans,Wirel。个人。交流。 6, 311 (1998)]用于表征天线网络中无线信息传输的香农容量。在该模型中,容量C是网络信道矩阵的线性统计量。我们使用这个事实来计算香农容量的方差 [C]。我们发现香农容量的期望值<C>是典型的,即变异系数$sqrt {{ m var} [C]}/langle C 角度$很小。 (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA,魏因海姆)
We consider a Rayleigh model [Foschini and Gans, Wirel. Pers. Commun. 6, 311 (1998)] for the Shannon capacity characterising wireless information transfer in a network of antennae. In this model, the capacity C is a linear statistic of the channel matrix of the network. We use this fact to calculate the variance [C] of the Shannon capacity. We find that the expected value 〈C〉 of the Shannon capacity is typical, that is the coefficient of variation $sqrt {{ m var} [C]}/langle C angle$ is small. (© 2004 WILEY‐VCH Verlag GmbH & Co.
