摘要：

In this paper we proposed a typical cooperative MIMO system grounded on wireless mobile ad hoc networks and brought forward the problem of time efficiency in cooperative MIMO system. And then adopting time efficiency, we analyzed the Shannon capacity limit of the cooperative MIMO system. The analysis shows two implications. First, only when intra-cluster channel is better enough than inter-cluster channel, cooperative MIMO can bring increment of channel capacity; second, there should be an optimal number of cooperative partners in a cooperative MIMO system. For instance it's optimal to use 3 cooperative partners in the proposed typical cooperative MIMO system, when it can achieve a channel capacity increment of about 2bps/hz compared with direct transmission.
