论文摘要
作为下一代无线通信的候选波形，广义频分复（GFDM）具有几种不错的属性，使其具有希望。在本文中，我们系统地概述了有关GFDM的研究。我们从GFDM收发器及其主要组件开始，该组件由原型滤波器设计，低复杂性收发器实现和符号检测算法组成。然后，我们研究了GFDM的几个非理想问题，包括同步问题，渠道估计以及相常/正交（I/Q）不平衡补偿。最后，我们研究了具有高光谱效率的基于GFDM的认知无线电和全双工无线电的应用。
As a candidate waveform for next-generation wireless communications, generalized frequency division multiplexing (GFDM) features several decent properties which make it promising. In this paper, we systematically overview the research about GFDM. We start with GFDM transceivers with their main components, which consist of prototype filter design, low-complexity transceiver implementation, and symbol detection algorithms. Then, we investigate a couple of non-ideal issues of GFDM, including synchronization issues, channel estimation, and in-phase/quadrature (I/Q) imbalance compensation. Lastly, we study the applications of GFDM-based cognitive radio and full-duplex radio which boast of a high spectral efficiency.
