中文摘要：
提出了一种基于协同机理的异构无线通信机制，研究了影响该异构协同通信系统分集传输性能的关键因素，从理论上给出了第二跳链路采用和不采用时间分集方案时中断概率和协同中继节点数量、第一跳和第二跳链路的信道增益、标称功率等的关系．数值分析结果表明异构协同分集性能主要受分集机制、协同中继节点数、第二跳链路小尺度衰落、标称功率等因素影响．
英文摘要：
A cooperative theorem based heterogeneous wireless communication mechanism is presented, and key factors impacting on the cooperative diversity of heterogeneous communications are evaluated. An outage probability analysis solution is presented for the second hop with/without time diversity schemes, which is related to the cooperation relay number, the channel gains of the first and the second hop, the normalized power, and etc. Numerical results show that there exists some main facts impacting on the relay channel＇s outage, such as diversity mechanisms, cooperative relay number, the second hop＇s small scale fading, and normalized power.
