Asymptotic Evaluation of Eigenvalue Distribution and Ergodic Capacity under Outdoor-Indoor MIMO Measured Channel

Abstract

This paper analyzes the asymptotic distribution of the channel eigenvalues and the asymptotic ergodic channel capacity using measured multiple-input multiple-output (MIMO) data. A realistic propagation environment in the presence of spatial fading correlation under an outdoor-indoor scenario at 5.25 GHz, which has important applications for data transmission in future cellular as well as wireless local area networks (WLAN) systems, is taken into account. The analytic results of the asymptotic distribution of the channel eigenvalues and the asymptotic ergodic channel capacity, which assume that the number of antenna elements approaches infinity, are reviewed. We show that these closed-form solutions are also valid for realistic channel and realistic number of antenna elements. In this paper, the outdoor-indoor scenario including the channels in an office room and corridors is investigated.
