摘要：

Distributed antenna system (DAS) can reduce the access distance and so lower the required transmit power compared with the conventional multiple input multiple out (MIMO) system. This paper investigated the information-theoretic capacity of DAS based on the channel model considering path loss, log-normal shadowing fading and Rayleigh fading. We find that the location of the receiver affects the DAS capacity and the difference between capacity with water-filling power allocation and that with equal-power allocation is significant. Furthermore, simulation results show that DAS offers large capacity gains over the traditional MIMO system.
