Journal of Physics: Conference Series Vol. 1889. P. 022091 (1-9)Abstract: In this paper, the authors investigate the issue of sampling clock offset (SCO) in fifth generation new radio systems. Due to the imperfect SCO estimation methods, the correction methods relying on the SCO estimation will not be perfect, so the proposed method directly corrects the effect of SCO without using any kind of estimation methods. Our method can work well in physical downlink shared channel (PDSCH) and use reference signals as recommended by the 3rd generation partnership project (3GPP) standards. Through system-level simulations, the obtained results show that the throughput of the system is improved where the gain difference between the proposed method and the case without SCO compensation arises to reach 25 % over tapped-line (TDL) channel.
