论文摘要
在这封信中,我们根据统计渠道状态信息(CSI)和瞬时S-> R CSI提出了两种功率分配方案,分别针对具有非再生网络编码的2-N-2合作多播系统的发射机,然后将隔离的预码器和分布式预码器分别提高到分布中,以提高分布式性能,以提高分布式性能。最后,我们证明了基于S-> R CSI的联合瞬时功率分配和分布式预编码器设计实现最佳性能。
In this letter, we propose two power allocation schemes based on the statistical channel state information (CSI) and instantaneous s->r CSI at transmitters respectively for a 2-N-2 cooperative multicast system with non-regenerative network coding.Then the isolated precoder and the distributed precoder are respectively applied to the schemes to further improve the system performance by achieving the full diversity gain. Finally, we demonstrate that joint instantaneous s->r CSI based power allocation and distributed precoder design achieve the best performance.
