| Abstract: | 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 ana-lyzed.And the development direction and application prospects of multi-node cooperation are pointed out. |
