Abstract

Distributed antenna systems (DAS) have gained wide spread interest as an efficient means to expand system capacity, decrease transmission power and mitigate inter cell interference. In this paper, a distributed MIMO-OFDM system is studied over composite Rayleigh-lognormal multipath fading channels. Two kinds of information-theoretic capacity measures - ergodic capacity and outage capacity are evaluated. We also investigate the impact of spatial fading correlation on the capacity. From simulation results, we find that the distributed MIMO-OFDM scheme can bring a certain degree of capacity improvement because of macroscopic shadow fading diversity gain. Moreover, we show that, due to the decrease in spatial fading correlation, the distributed MIMO-OFDM scheme can provide capacity improvement compared with the conventional centralized MIMO-OFDM scheme.
