To solve the problem that some user nodes can not set multi-antenna, a multi-node cooperative communications technology is proposed to form multi-antenna array. Multi-node cooperation is a new spa- tial diversity and it achieves the diversity gain by sharing their antennas and relaying information. The key technologies of cooperative communications are studied and performance gain of cooperative diversity is analyzed. And the development direction and application prospects of multi-node cooperation are pointed out.
