摘　　要：提出了一种基于Alamouti模型的差分检测方案,通过对发射符号进行相位旋转,携带附加角度信息,获得更高的频谱效率。仿真结果表明:通过发送端携带附加角度信息,能获得更高的频谱效率。同时,方案中的角度旋转思想有望在其它差分检测方案中得到应用。A differential detection scheme is proposed which is based on Alamouti＇s transmission scheme, and the proposed scheme can provide higher spectrum efficiency with phase rotation. The simulation results show that the proposed scheme increases the spectrum efficiency because of the angle information. On the other hand, the idea of angle rotation in this scheme can potentially be used in other differential detection scheme.
