摘要

介绍了一种称为软决策转发(SDF)的协作协议。SDF协议利用中继节点接收信号的软判决值。Alamouti码用于正交传输，分布式空时码用于非正交传输。提出了具有较低解码复杂度的最大似然解码器。通过仿真可以看出，SDF协议优于AF协议。

Soft-decision-and-forward protocol for cooperative communication networks based on Alamouti code

A cooperative protocol called soft-decision-and-forward (SDF) is introduced. SDF protocol exploits the soft decision values of the received signal at the relay node. Alamouti code is used for orthogonal transmission and distributed space-time codes are designed for non-orthogonal transmission. The maximum likelihood decoders with low decoding complexity are proposed. From simulations, it can be seen that SDF protocol outperforms AF protocol.
