论文摘要
在本文中，我们分析了多载波（MC）全双工（FD）的渐近率，大量多重输入多重输出（MMIMO）解码和正向（DF）继电器系统，该系统为多个MC单甲烷半数（HD）节点提供服务。我们考虑了导致残留自我干扰（SI）和载波泄漏（ICL）的硬件扭曲的影响，以及不完美的通道状态信息（CSI）的影响。当天线数量变大时，我们得出了最大比率传输（MRT）/最大比率组合（MRC）策略的系统的渐近率表达（转至$ \ infty $）。人们注意到，在大型天线阵列制度中，硬件失真的影响变得显着。与多用户干扰和接收器噪声的效果相反，随着中继天线的数量流向无穷大，由硬件损伤引起的残留Si和ICL仍在MC系统中。
In this paper, we analyze the asymptotic rate for a multi-carrier (MC) full-duplex (FD) massive multiple input multiple output (mMIMO) decode and forward (DF) relay system which serves multiple MC single-antenna half-duplex (HD) nodes. We take into account the impact of hardware distortions resulting in residual self-interference (SI) and inter-carrier leakage (ICL) as well as the impact of imperfect channel state information (CSI). We derive the asymptotic rate expression of our system employed with maximum ratio transmitting (MRT)/ maximum ratio combining (MRC) strategy when the number of the antenna becomes large (goes to $\infty$). It is noticed that the impact of hardware distortion becomes remarkable in a large-scale antenna array regime. On contrary to the effect of multi-user interference and receiver noise, which vanishes as the number of relay antenna goes to infinity, the residual SI and ICL caused by the hardware impairments remains in the MC system.
