我们推导出理论比特和帧错误率表达式的解码和转发（DF）协作网络containingMusers，采用各种分组码在瑞利块衰落信道。借助这些表达式，我们探讨了这种系统的自适应功率控制的性能。这扩展了以前的工作，优化所有中继和直接通道的功率分配。我们进一步扩展我们的工作，各种合作机制，我们得出结论，功率控制可以大大有利于DF协作网络在衰落环境中。
We derive theoretical bit and frame error rate expressions for decode-and-forward (DF) collaborative networks containingMusers, employing a variety of block codes over a Rayleigh block faded channel. With the aid of these expressions, we explore the performance of adaptive power control for such systems. This extends previous work by optimizing power allocation for all relay and direct channels. We further extend our work to a variety of cooperation mechanisms and we conclude that power control can greatly benefit a DF collaborative network in a fading environment.
