Coordinated multiple point transmission and reception can reduce system interference and Distributed Antenna Systems can enlarge wireless coverage with lower transmitting power. These two techniques introduce the flexibility of wireless network architecture design for green communications. In this paper, we extend wireless network architecture with cooperative distributed antenna systems and derive the downlink ergodic capacity in three different kinds of wireless coverage areas. Then, analytical expressions of the downlink ergodic capacity are verified by system simulation. The research results prove that combination of cooperative and DAS can provide beneficial to green wireless communications systems.
