摘要

基于偏置正交调幅的滤波器组多载波(OQAM-FBMC)是未来无线通信系统中很有前途的一种波形。尽管有许多优点，OQAM-FBMC在双选择信道中存在高信号失真，在这种情况下，简单的均衡不足以解决这个问题。为了提高OQAM-FBMC技术的效率，本文提出了一种集成MMSE均衡器的混合自动重复请求(HARQ)方案。此外，我们利用累积分布函数(CDF)分析了新技术对载波间干扰(ICI)的影响。仿真结果表明，该方法在块错误率(BLER)方面有显著提高。

An MMSE Integrated Equalization for HARQ Chase Combining in OQAM-FBMC systems

Offset quadrature amplitude modulation-based filter bank multicarrier (OQAM-FBMC) is a promising waveform for future wireless communication systems. Despite its numerous advantages, OQAM-FBMC suffers from high signal distortions in a doubly selective channel where a simple equalization is not sufficient to deal with this issue. In this paper, we propose a hybrid automatic repeat request (HARQ) scheme with integrated MMSE equalizer to improve the efficiency of OQAM-FBMC technique. In addition, we analyse the impact of the new technique on inter-carrier interference (ICI) using the cumulative distribution function (CDF). Simulation results show that the proposed approach provides a significant gain in terms of block error rate (BLER).
