Fluctuations of the Shannon capacity in a Raleigh model of wireless communication

Abstract

Using the fact that the Shannon capacity C of a Raleigh model of wireless channels is a linear statistic of the channel matrix, we calculate its variance var[C]. We find that the expected value <C> of the Shannon capacity is typical in the model considered, that is the coefficient of variation (var[C])^(1/2)/<C> is small.
