论文摘要
这封信的重点是带有无线再生网络编码（RNC）的基本多播单元的电力分配方案。在RNC中，从两个源接收到的混合信号由继电器共同解码，该继电器在复合场（RCNC）或Galois Field（RGNC）中超级构造符号，然后再重新启动。我们推断基于最佳统计通道状态信息（CSI）的功率分配，并在两个RNC之间进行比较。当每个发射器上有瞬时CSI可用时，我们提出了RCNC的次优功率分配，可实现更好的性能。
This letter focuses on power allocation schemes for a basic multicast cell with wireless regenerative network coding (RNC). In RNC, mixed signals received from the two sources are jointly decoded by the relay where decoded symbols are superposed in either the complex field (RCNC) or Galois field (RGNC) before being retransmitted. We deduce the optimal statistical channels state information (CSI) based power allocation and give a comparison between the two RNCs. When instantaneous CSI is available at each transmitter, we propose a suboptimal power allocation for RCNC, which achieves better performance.
