Abstract

Distributed multiple-input multiple-output (MIMO) system combines the advantages of point-to-point MIMO systems and distributed antenna systems, and improves link quality and coverage. In this paper, a distributed MIMO channel model which comprises relative path loss, correlated shadow fading and correlated small scale fading is proposed. The impact of two kinds of fading correlation and transmit power allocation on capacity of distributed MIMO channel is investigated and compared carefully by Monte Carlo simulations, and the characteristics of capacity space distribution of distributed MIMO channel with spatial shadowing correlation are also obtained.
