摘要

物理层网络编码(PNC)利用信号传播的叠加，有可能提高无线中继通信的频谱效率。在理想情况下，与传统的时分复用相比，PNC可以使对称中继网络的吞吐量增加一倍。然而，在实践中，不完善的信道条件和硬件可能导致中继接收器的时间和频率偏移，从而降低PNC性能。

Frequency offset compensation in physical-layer network coding systems

Physical layer network coding (PNC) has the potential to improve the spectral efficiency of wireless relay communications by utilising the superposition of signal propagation. In the ideal case, PNC can double the throughput of a symmetric relay network when compared to conventional time division multiplexing. However, in practice imperfect channel conditions and hardware can lead to time and frequency offsets at the relay receiver that degrade PNC performance.
