摘要

基于正交调幅的滤波器组多载波(QAM-FBMC)是5G及以后的一项有前途的技术。与OFDM相比,QAM-FBMC可以提供更好的频谱约束和更低的带外发射(OOBE)。这些优点的代价是高固有干扰和误码率(BER)下降。在本文中,我们提出了不同的接收机来提高QAM-FBMC系统的性能。仿真结果表明,基于最小均方误差(MMSE)和迭代干扰抵消(IIC)的接收机能够显著提高系统性能。

Advanced receivers for QAM-FBMC systems with short filters
Quadrature amplitude modulation based Filter-bank multicarrier (QAM-FBMC) is a promising technology for 5G and beyond. Compared to OFDM, QAM-FBMC can provide better spectral confinement and lower out-of-band emissions (OOBE). These advantages come with the cost of high intrinsic interference and bit error rate (BER) degradation. In this paper, we propose different receivers to improve the performance of the QAM-FBMC systems. The simulation results show that the proposed receivers, based on minimum mean square error (MMSE) and iterative interference cancellation (IIC), are able to significantly enhance the system performance.
