| 摘 要： | 针对一个发送端、接收端及每个中继都配置单根天线的无线中继网络,在假设中继不知道任何信道信息的条件下,为了提高系统性能,本文提出中继选择与分布式空时码相结合的方案.证明了选择2个中继与Alamouti正交空时码的结合方案成对错误概率的Chernoff上界要比对应的只选择2个中继参加协作不使用Alamouti正交空时码的情...

| Abstract: | Under an assumption that each relay has no any channel information in a wireless relay network in which every transmitter,receiver and relay is equipped with a single antenna respectively,a scheme combining distributed space time code with the relay selection is proposed in order to improve the performance of the system in this paper.It is proved that the Chernoff bound of the pair-wise error probability(PEP) of this combination scheme is much lower than the scheme without applying Alamouti orthogonal space... |
