Remote Antenna Unit (RAU) location in Distributed Antenna Systems (DAS) will influence the system capacity of wireless network. In this paper, the downlink ergodic system capacity for cooperative distributed antenna systems with multiple antennas RAUs in a composite fading channel was analyzed and an calculation algorithm was proposed for optimal placement of RAUs in cooperative distributed wireless network. Numerical results had verified correctness of analytical results of downlink ergodie system capacity and also showed that RAU location add a flexible factor for the spectrum efficiency enhancement.
