摘要

高精度宽带信号传输对于5G及以上无线通信系统至关重要。发射机的存储非线性是一个严重的问题，因为它会降低信号质量，降低系统性能。研究了一种由频域均衡器(FDEs)和盲非线性补偿器(BNLC)组成的接收后非线性补偿方案。采用频域记忆非线性建模方法，通过计算机仿真对几种具有fde和BNLC的PRC结构进行了评价。结果表明，所提出的PRC方案可以通过频率选择传播信道有效地补偿宽带发射机中的存储非线性。通过在基站中实施PRC，上行链路性能将得到增强，而不会在用户终端中产生任何额外的成本和功耗。

Compensation of Transmitter Memory Nonlinearity by Post-Reception Blind Nonlinear Compensator with FDE

SUMMARY High-accuracy wideband signal transmission is essential for 5G and Beyond wireless communication systems. Memory nonlinearity in transmitters is a serious issue for the goal, because it deteriorates the quality of signal and lowers the system performance. This paper studies a post-reception nonlinear compensation (PRC) schemes consisting of frequency domain equalizers (FDEs) and a blind nonlinear compensator (BNLC). A frequency-domain memory nonlinearity modeling approach is employed, and several PRC conﬁgurations with FDEs and BNLC are evaluated through computer simulations. It is concluded that the proposed PRC schemes can e ﬀ ectively compensate memory nonlinearity in wide-band transmitters via frequency-selective propagation channel. By implementing the PRC in a base station, uplink performance will be enhanced without any additional cost and power consumption in user terminals.
