N2 - In this paper, we analyze and optimize the ergodic capacity for a downlink multi-cell multi-user distributed multiple input multiple output (MIMO) system. We first derive the system ergodic capacity by using the approximated Gamma distribution. In order to maximize the system capacity, an optimization problem with respect to the number of remote access unit (Rau) antennas and the number of users is formulated. Then an iteration algorithm is proposed to obtain the optimization configuration of Rau antennas and users. Our simulation results show that the proposed algorithm can obtain the optimal configuration of Rau antennas and supportable users to maximize the system ergodic capacity.
